Key Takeaways The three main types of betting odds are fractional British odds, decimal European odds, and American moneyline odds. These are simply different ways of presenting the same thing, and hold no difference in terms of payouts.

Learn About Conditional Probability Conditional probability is the chances of an event or outcome that is itself based on the occurrence of some other previous event or outcome.

Martingale System Definition The Martingale system is a system in which the dollar value of trades increases after losses, or position size increases with a smaller portfolio size. Dutch Book Theorem Definition Dutch Book Theorem is a type of probability theory that postulates profit opportunities will arise when inconsistent probabilities are assumed in a given context.

Lump-Sum Distribution A lump-sum distribution is a one-time payment for an entire amount due, rather than payments broken into smaller installments. Because the bookmakers margins are worked into the percentage so that they can make their money. See below for more details. For this example lets use divided by 2. All sports betting comes down to chance. There is the dilemma and how much would you be prepared to risk in either scenario?

Bookmakers have banks of traders and analysts figuring out the probability of outcomes and then they set the odds from there. Anything on the odds-on side of that and you are increasing probability percentages. Anything longer than Even Money is decreasing the probability percentage of an outcome happening. There is a thing called bookmaker margins. This is where a bookmaker makes their profit and you can see it in action.

In a football match where there are three outcomes, you can add up the odds to just how the bookmaker makes their money. On an event with two outcomes, say a tennis match, one player is trading at 1. So it is If the punter won five times out of ten, the bookmaker would be even at the end of the day, with no profit. Now and again you may come across US odds or a Moneyline which may look a bit confusing.

The odds in favor of an event or a proposition is the ratio of the probability that the event will happen to the probability that the event will not happen. Mathematically, this is a Bernoulli trial , as it has exactly two outcomes. In case of a finite sample space of equally likely outcomes , this is the ratio of the number of outcomes where the event occurs to the number of outcomes where the event does not occur; these can be represented as W and L for Wins and Losses or S and F for Success and Failure.

For example, the odds that a randomly chosen day of the week is a weekend are two to five , as days of the week form a sample space of seven outcomes, and the event occurs for two of the outcomes Saturday and Sunday , and not for the other five. For example, the odds against a random day of the week being a weekend are Odds and probability can be expressed in prose via the prepositions to and in: "odds of so many to so many on or against [some event]" refers to odds — the ratio of numbers of equally likely outcomes in favor and against or vice versa ; "chances of so many [outcomes], in so many [outcomes]" refers to probability — the number of equally like outcomes in favour relative to the number for and against combined.

For example, "odds of a weekend are 2 to 5", while "chances of a weekend are 2 in 7". In casual use, the words odds and chances or chance are often used interchangeably to vaguely indicate some measure of odds or probability, though the intended meaning can be deduced by noting whether the preposition between the two numbers is to or in. Odds can be expressed as a ratio of two numbers, in which case it is not unique — scaling both terms by the same factor does not change the proportions: odds and odds are the same even odds.

Odds can also be expressed as a number, by dividing the terms in the ratio — in this case it is unique different fractions can represent the same rational number. Odds as a ratio, odds as a number, and probability also a number are related by simple formulas, and similarly odds in favor and odds against, and probability of success and probability of failure have simple relations. Analogously, given odds as a ratio, the probability of success or failure can be computed by dividing, and the probability of success and probability of failure sum to unity one , as they are the only possible outcomes.

In case of a finite number of equally likely outcomes, this can be interpreted as the number of outcomes where the event occurs divided by the total number of events:. This is a minor difference if the probability is small close to zero, or "long odds" , but is a major difference if the probability is large close to one.

These transforms have certain special geometric properties: the conversions between odds for and odds against resp. They are thus specified by three points sharply 3-transitive. Swapping odds for and odds against swaps 0 and infinity, fixing 1, while swapping probability of success with probability of failure swaps 0 and 1, fixing. Converting odds to probability fixes 0, sends infinity to 1, and sends 1 to.

In probability theory and statistics, odds and similar ratios may be more natural or more convenient than probabilities. In some cases the log-odds are used, which is the logit of the probability. Most simply, odds are frequently multiplied or divided, and log converts multiplication to addition and division to subtractions. This is particularly important in the logistic model , in which the log-odds of the target variable are a linear combination of the observed variables.

Similar ratios are used elsewhere in statistics; of central importance is the likelihood ratio in likelihoodist statistics , which is used in Bayesian statistics as the Bayes factor. Odds are particularly useful in problems of sequential decision making, as for instance in problems of how to stop online on a last specific event which is solved by the odds algorithm.

The odds are a ratio of probabilities; an odds ratio is a ratio of odds, that is, a ratio of ratios of probabilities. Odds-ratios are often used in analysis of clinical trials. Answer: The odds in favour of a blue marble are One can equivalently say, that the odds are against. There are 2 out of 15 chances in favour of blue, 13 out of 15 against blue. That value may be regarded as the relative probability the event will happen, expressed as a fraction if it is less than 1 , or a multiple if it is equal to or greater than one of the likelihood that the event will not happen.

In the first example at top, saying the odds of a Sunday are "one to six" or, less commonly, "one-sixth" means the probability of picking a Sunday randomly is one-sixth the probability of not picking a Sunday. While the mathematical probability of an event has a value in the range from zero to one, "the odds" in favor of that same event lie between zero and infinity.

It is 6 times as likely that a random day is not a Sunday. The use of odds in gambling facilitates betting on events where the relative probabilities of outcomes varied. For example, on a coin toss or a match race between two evenly matched horses, it is reasonable for two people to wager level stakes. However, in more variable situations, such as a multi-runner horse race or a football match between two unequally matched sides, betting "at odds" provides a perspective on the relative likelihoods of the possible outcomes.

In the modern era, most fixed odds betting takes place between a betting organisation, such as a bookmaker , and an individual, rather than between individuals. Different traditions have grown up in how to express odds to customers, older eras came with betting odds between people, today which is illegal in most countries, it was referred as "odding", an underground slang word with origins based in the Bronx.

Favoured by bookmakers in the United Kingdom and Ireland , and also common in horse racing , fractional odds quote the net total that will be paid out to the bettor, should he or she win, relative to the stake. However, not all fractional odds are traditionally read using the lowest common denominator. Fractional odds are also known as British odds, UK odds, [10] or, in that country, traditional odds.

Odds with a denominator of 1 are often presented in listings as the numerator only. A variation of fractional odds is known as Hong Kong odds. Fractional and Hong Kong odds are actually exchangeable. The only difference is that the UK odds are presented as a fractional notation e.

Both exhibit the net return. The European odds also represent the potential winnings net returns , but in addition they factor in the stake e. Favoured in continental Europe , Australia , New Zealand , Canada , and Singapore , decimal odds quote the ratio of the payout amount, including the original stake, to the stake itself.

Therefore, the decimal odds of an outcome are equivalent to the decimal value of the fractional odds plus one. This is considered to be ideal for parlay betting, because the odds to be paid out are simply the product of the odds for each outcome wagered on. When looking at decimal odds in betting terms, the underdog has the higher of the two decimals, while the favorite has the lower of the two.

Decimal odds are favoured by betting exchanges because they are the easiest to work with for trading, as they reflect the inverse of the probability of an outcome. Decimal odds are also known as European odds , digital odds or continental odds. Moneyline odds are favoured by American bookmakers. The figure quoted is either positive or negative.

Moneyline odds are often referred to as American odds. A "moneyline" wager refers to odds on the straight-up outcome of a game with no consideration to a point spread. In most cases, the favorite will have negative moneyline odds less payoff for a safer bet and the underdog will have positive moneyline odds more payoff for a risky bet.

However, if the teams are evenly matched, both teams can have a negative line at the same time e. In gambling, the odds on display do not represent the true chances as imagined by the bookmaker that the event will or will not occur, but are the amount that the bookmaker will pay out on a winning bet, together with the required stake.

In formulating the odds to display the bookmaker will have included a profit margin which effectively means that the payout to a successful bettor is less than that represented by the true chance of the event occurring. For many, decimal is preferable. Now we want to see what those odds mean in terms of probability. So there are the probability outcomes for the match. Because the bookmakers margins are worked into the percentage so that they can make their money.

See below for more details. For this example lets use divided by 2. All sports betting comes down to chance. There is the dilemma and how much would you be prepared to risk in either scenario?

On an event with two outcomes, say a tennis match, one player is trading at 1.

In other words, your stake is already included in the decimal number no need to add back your stake , which makes its total payout calculation easier. The total potential return on a stake can be calculated as:. For instance, one of the renowned betting websites priced the candidates to win the U. Presidential Election. Donald Trump: 4. The higher the total payout i.

In both cases, you get your initial wager back, in addition to the amount won. The difference between the odds for the favorite and the underdog widens as the probability of winning for the favorite increases. In this matchup, there is a big difference between the two odds, indicating a much higher probability of Duke winning the game and advancing to the next round of the NCAA Tournament. If you are planning to enter the betting or the gambling world, it is important to be able to understand and interpret all types of odds well.

With horse racing you are betting against other betters. Once the winning horse has crossed the finish line, the house will deduct its take and the remaining amount is then divided among the people who bet on the winning horse.

Unlike with win bets, there are no exact horse racing odds for exotic bets because there are too many variables. Yet at Amwager, we post probable payouts for exacta and daily double wagers. Also for exotic wagers, the payouts are calculated differently. Your payout is calculated by subtracting the amount of winning dollars from the total pool, then dividing the remaining pool by the amount of cash bet on the winner, and finally adding back in the winning bet amount.

For easy math, we used round numbers. But in the real world, this does not always happen. Payouts use the actual odds and are rounded down to the nearest nickel or dime, depending on the rules of the racetrack. This rounding is called breakage. This is why every racetrack has television simulcast commentator who handicaps between the races as well as publishing handicapping tip sheets to help you place your bets.

At AmWager, we have our own horse racing handicapper that gives expert picks on upcoming races. Now that you know how to read and calculate horse racing odds, you are ready to take the bet!

They are just different ways of conveying the same information but they do add another layer of complexity. Thankfully, it only requires simple maths. To go from a fraction to a decimal is as easy as dividing out the fraction and adding one. If you want to go from decimal odds to fractional odds is similarly simple. Any price above evens is known as odds against, while anything below evens is odds on.

A long odds shot will provide you with a bigger win but is much less likely to win. Betting Odds Explained. An example of the various odds available on a typical betting market.

American odds start with either a positive or negative sign e. When it comes to calculating the return from a bet made using American odds there are two different formulas that can be used:.

This means that the team you are betting on must win or not lose by a predetermined margin of points. Fractional odds are some of the most simple to understand, as they present your potential winnings as a fraction of the money you stake: while the denominator represents the amount bet, the numerator is the amount your stake will yield in a winning bet. Want a real-life example? You can use the following formula to calculate potential returns with fractional odds:.

The decimal odds format, also known as European odds, represents the multiple of your stake that you will get back for winning a bet. While these are more common at overseas betting exchanges, you may see these at US betting sites. For example, betting on a market priced at 2. Another example of decimal odds in action would be betting on NHL game with odds of 9. You can use the following formula to calculate potential returns with decimal odds:. Whichever format odds are written in, they all have an equivalent in another format.

Not only will this help you understand your potential return, but it also makes it easier to compare betting odds across sportsbooks. As the US sports betting industry continues to grow, so does the selection betting options, or betting markets, at each site.

A parlay wager is a single bet that is linked with two or more wagers.

While all of those numbers on the board may seem imposing, the odds and payoffs are actually pretty easy to learn. And by doing so, you will be able to make and calculate better bets. The easiest information on the board is the win odds quoted on each horse. They don't tell you what the horse will pay, but the amount of profit you will get and the amount you have to bet to get it.

Payoffs use the actual odds and are rounded down to the nearest nickel or dime, depending on the rules at that track. This rounding is called breakage. If you want to calculate the exact win odds on a horse, you will need to use a couple of other figures from the tote board:. Before the track pays off the winners, they deduct the "take," which is generally between 14 and 20 percent and is different in every state.

This money goes to pay state and local taxes, payment for the horsemen, expenses at the track, and the track's profit. While these are more common at overseas betting exchanges, you may see these at US betting sites. For example, betting on a market priced at 2. Another example of decimal odds in action would be betting on NHL game with odds of 9. You can use the following formula to calculate potential returns with decimal odds:.
