Understanding betting odds -

Probability can be calculated via the odds of an outcome happening, with you being able to use probability to work out how likely an outcome is to happen. The below examples can be used to help understand how decimal odds can be used to work out the probability of an outcome occurring:. When using fractional odds, you can work out your winnings by just using the numbers included in the fraction.

The first number of the fraction indicates how much profit you would make if you staked the second number of the fraction. Decimal odds are also fairly easy to work out, with you just needing to multiply the odds by your stake to work out your winnings.

The numerator of the fraction shows how much you stand to make as profit should you stake the denominator. They can also be used to show the probability of a bet, with top heavy fractions being less likely to occur, whilst bottom heavy fractions are more likely to happen.

Decimal odds are less commonly used in the UK, however they do prove to be much easier to understand. The number itself shows the amount your bet will return for every £1 staked, as well as the probability of the outcome occurring.

To work out your potential returns, all you have to do is multiply your stake by the decimal odds, with your stake then automatically being included in this total payout. For example, if you stake £1 on a bet with odds of 5. To calculate the odds of winning a bet in a casino game, you'll need to know the number of possible outcomes that would result in a win and the total number of possible outcomes.

A betting opportunity should be considered valuable if the probability assessed for an outcome is higher than the implied probability estimated by the bookmaker.

Furthermore, the odds on display never reflect the true probability of an event occurring or not occurring. The payoff on a win is always less than what one should have received if the odds had reflected the true chances.

Key Takeaways The three types of odds are fractional, decimal, and moneyline also known as "American" odds. One type of odds can be converted into another, and may also be expressed as an implied probability percentage.

A key to assessing an interesting opportunity is determining if a probability is actually higher than the implied probability reflected in the odds. Technically, the house always wins because the bookmaker's profit margin is also factored into the odds.

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. 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 teams, betting "at odds" provides the possibility to take the respective likelihoods of the possible outcomes into account.

The use of odds in gambling facilitates betting on events where the probabilities of different outcomes vary. In the modern era, most fixed-odd 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. 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 they win, relative to the stake.

The numerator and denominator of fractional odds are always integers , thus if the bookmaker's payout was to be £1. 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.

This profit is known as the 'overround' on the 'book' the 'book' refers to the old-fashioned ledger in which wagers were recorded, and is the derivation of the term 'bookmaker' and relates to the sum of the 'odds' in the following way:.

The true odds against winning for each of the three horses are 1—1, 3—2 and 9—1, respectively. This represents the odds against each, which are 4—6, 1—1 and 4—1, in order. This value of 30 represents the amount of profit for the bookmaker if he gets bets in good proportions on each of the horses.
