Using an example of decimal odds, a candidate has 2. If so, the implied probability is Therefore, the implied probability equals Moreover, the odds displayed by different bookmakers can vary significantly, meaning that the odds displayed by a bookmaker are not always correct. The key is to consider a betting opportunity valuable when the probability assessed for an outcome is higher than the implied probability estimated by the bookmaker.
The odds on display never reflect the true probability or chance of an event occurring or not occurring. There is always a profit margin added by the bookmaker in these odds, which means that the payout to the successful punter is always less than what they should have received if the odds had reflected the true chances. The bookmaker needs to estimate the true probability or chance of an outcome correctly in order to set the odds on display in such a way that it profits the bookmaker regardless of an event outcome.
If you notice, the total of these probabilities is This is because the odds on display are not fair odds. The bookie has an edge built into the odds. According to a study published in the Journal of Gambling Studies , the more hands a player wins, the less money they are likely to collect, especially with respect to novice players. Behavioral economics comes into play here.
A player continues playing the lottery , either in hopes of a big gain that would eventually offset the losses or the winning streak compels the player to keep playing. In both cases, it is not rational or statistical reasoning but the emotional high of a win that motivates them to play further. Consider a casino. The house wants you to stay and continue playing. Naturally, the games offered by the casino have a built-in house edge, although the house advantage varies with the game. Moreover, novices find it particularly difficult to do cognitive accounting and people often misjudge the variance of payouts when they have a streak of wins, ignoring the fact that frequent modest gains are eventually erased by losses, which are often less frequent and larger in size.
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. Science Daily.

Combinatorial calculus is an important part of gambling probability applications. In games of chance, most of the gambling probability calculus in which we use the classical definition of probability reverts to counting combinations.
The gaming events can be identified with sets, which often are sets of combinations. Thus, we can identify an event with a combination. For example, in a five draw poker game, the event at least one player holds a four of a kind formation can be identified with the set of all combinations of xxxxy type, where x and y are distinct values of cards. These can be identified with elementary events that the event to be measured consists of.
Games of chance are not merely pure applications of probability calculus and gaming situations are not just isolated events whose numerical probability is well established through mathematical methods; they are also games whose progress is influenced by human action.
In gambling, the human element has a striking character. The player is not only interested in the mathematical probability of the various gaming events, but he or she has expectations from the games while a major interaction exists. To obtain favorable results from this interaction, gamblers take into account all possible information, including statistics , to build gaming strategies. The oldest and most common betting system is the martingale, or doubling-up, system on even-money bets, in which bets are doubled progressively after each loss until a win occurs.
This system probably dates back to the invention of the roulette wheel. Thus, it represents the average amount one expects to win per bet if bets with identical odds are repeated many times. A game or situation in which the expected value for the player is zero no net gain nor loss is called a fair game. The attribute fair refers not to the technical process of the game, but to the chance balance house bank —player.
Even though the randomness inherent in games of chance would seem to ensure their fairness at least with respect to the players around a table—shuffling a deck or spinning a wheel do not favor any player except if they are fraudulent , gamblers always search and wait for irregularities in this randomness that will allow them to win. It has been mathematically proved that, in ideal conditions of randomness, and with negative expectation, no long-run regular winning is possible for players of games of chance.
Most gamblers accept this premise, but still work on strategies to make them win either in the short term or over the long run. Casino games provide a predictable long-term advantage to the casino, or "house" while offering the player the possibility of a large short-term payout.
Some casino games have a skill element, where the player makes decisions; such games are called "random with a tactical element. For more examples see Advantage gambling. The player's disadvantage is a result of the casino not paying winning wagers according to the game's "true odds", which are the payouts that would be expected considering the odds of a wager either winning or losing.
However, the casino may only pay 4 times the amount wagered for a winning wager. The house edge HE or vigorish is defined as the casino profit expressed as a percentage of the player's original bet. In games such as Blackjack or Spanish 21 , the final bet may be several times the original bet, if the player doubles or splits. Example: In American Roulette , there are two zeroes and 36 non-zero numbers 18 red and 18 black.
Therefore, the house edge is 5. The house edge of casino games varies greatly with the game. The calculation of the Roulette house edge was a trivial exercise; for other games, this is not usually the case. In games that have a skill element, such as Blackjack or Spanish 21 , the house edge is defined as the house advantage from optimal play without the use of advanced techniques such as card counting or shuffle tracking , on the first hand of the shoe the container that holds the cards.
The set of the optimal plays for all possible hands is known as "basic strategy" and is highly dependent on the specific rules, and even the number of decks used. Good Blackjack and Spanish 21 games have to house edges below 0.
Online slot games often have a published Return to Player RTP percentage that determines the theoretical house edge. Some software developers choose to publish the RTP of their slot games while others do not. The luck factor in a casino game is quantified using standard deviation SD. The standard deviation of a simple game like Roulette can be simply calculated because of the binomial distribution of successes assuming a result of 1 unit for a win, and 0 units for a loss.
Furthermore, if we flat bet at 10 units per round instead of 1 unit, the range of possible outcomes increases 10 fold. After enough large number of rounds the theoretical distribution of the total win converges to the normal distribution , giving a good possibility to forecast the possible win or loss.
The 3 sigma range is six times the standard deviation: three above the mean, and three below. There is still a ca. The standard deviation for the even-money Roulette bet is one of the lowest out of all casinos games. Most games, particularly slots, have extremely high standard deviations. As the size of the potential payouts increase, so does the standard deviation. Unfortunately, the above considerations for small numbers of rounds are incorrect, because the distribution is far from normal.

In gambling parlance, making a book is the practice of laying bets on the various possible outcomes of a single event. The term originates from the practice of recording such wagers in a hard-bound ledger the 'book' and gives the English language the term bookmaker for the person laying the bets and thus 'making the book'. A bookmaker strives to accept bets on the outcome of an event in the right proportions in order to make a profit regardless of which outcome prevails.
See Dutch book and coherence philosophical gambling strategy. This is achieved primarily by adjusting what are determined to be the true odds of the various outcomes of an event in a downward fashion i. The odds quoted for a particular event may be fixed but are more likely to fluctuate in order to take account of the size of wagers placed by the bettors in the run-up to the actual event e.
This article explains the mathematics of making a book in the simpler case of the former event. For the second method, see Parimutuel betting. It is important to understand the relationship between fractional and decimal odds. Multiplying both a and b by the same number gives odds equivalent to a-b. Decimal odds are a single value, greater than 1, representing the amount to be paid out for each unit bet.
The equivalent decimal odds are 2. Hence, fractional odds of a-1 ie. In considering a football match the event that can be either a 'home win', 'draw' or 'away win' the outcomes then the following odds might be encountered to represent the true chance of each of the three outcomes:. These odds can be represented as implied probabilities or percentages by multiplying by as follows:. The bookmaker, in his wish to avail himself of a profit, will invariably reduce these odds.
Consider the simplest model of reducing, which uses a proportional decreasing of odds. For the above example, the following odds are in the same proportion with regard to their implied probabilities :. Examining how he potentially achieves this:.
In reality, bookmakers use models of reducing that are more complicated than the model of the "ideal" situation. Bookmaker margin in English football leagues decreased in recent years. When a punter bettor combines more than one selection in, for example, a double , treble or accumulator then the effect of the overround in the book of each selection is compounded to the detriment of the punter in terms of the financial return compared to the true odds of all of the selections winning and thus resulting in a successful bet.
To explain the concept in the most basic of situations an example consisting of a double made up of selecting the winner from each of two tennis matches will be looked at:. In Match 1 between players A and B both players are assessed to have an equal chance of winning.
The situation is the same in Match 2 between players C and D. In a fair book in each of their matches, i. However, a bookmaker would probably offer odds of for example on each of the two possible outcomes in each event each tennis match. This results in a book for each of the tennis matches of The decimal odds of a multiple bet is often calculated by multiplying the decimal odds of the individual bets, the idea being that if the events are independent then the implied probability should be the product of the implied probabilities of the individual bets.
This represents an implied probability of Thus the overround has slightly more than doubled by combining two single bets into a double. This is why bookmakers offer bets such as Lucky 15 , Lucky 31 and Lucky 63 ; offering double the odds for one winner and increasing percentage bonuses for two, three and more winners.
In general, for any accumulator bet from two to i selections, the combined percentage overround of books of B 1 , B 2 , In settling winning bets either decimal odds are used or one is added to the fractional odds: this is to include the stake in the return. The place part of each-way bets is calculated separately from the win part; the method is identical but the odds are reduced by whatever the place factor is for the particular event see Accumulator below for detailed example.
All bets are taken as 'win' bets unless 'each-way' is specifically stated. Non-runners are treated as winners with fractional odds of zero decimal odds of 1. Fractions of pence in total winnings are invariably rounded down by bookmakers to the nearest penny below. Calculations below for multiple-bet wagers result in totals being shown for the separate categories e.
Each-Way multiple bets are usually settled using a default " Win to Win, Place to Place " method, meaning that the bet consists of a win accumulator and a separate place accumulator Note: a double or treble is an accumulator with 2 or 3 selections respectively.
However, a more uncommon way of settling these type of bets is " Each-Way all Each-Way " known as " Equally Divided ", which must normally be requested as such on the betting slip in which the returns from one selection in the accumulator are split to form an equal-stake each-way bet on the next selection and so on until all selections have been used. Double  . Note: " Win to Win, Place to Place " will always provide a greater return if all selections win, whereas " Each-Way all Each-Way " provides greater compensation if one selection is a loser as each of the other winners provide a greater amount of place money for subsequent selections.
Treble  . Accumulator  . Note: 'All up to win' means there are insufficient participants in the event for place odds to be given e.
