With the advent of Internet and bet exchange betting, the possibility of fixed-odds arbitrage actions and Dutch books against bookmakers and exchanges has expanded significantly. Betting exchanges in particular act like a stock exchange , allowing the odds to be set in the course of trading between individual bettors, usually leading to quoted odds that are reasonably close to the "true odds. In making a bet where the expected value is positive, one is said to be getting "the best of it".
However, if someone offered odds of 10 to 1 that a card chosen at random from a regular 52 card deck would be the ace of spades, one would be getting "the worst of it" because the chance is only 1 in 52 that the ace will be chosen.
Player A wins if the dice add up to 12, of which there is only one possible case. Player B wins if the dice fall in any other combination, of which there are 35 possibilities. When making a bet in which one must put more at risk than one can win, one is laying the odds. Rational bettors will do so only if the actual chances of an adverse outcome are low enough that the expected outcome even after deduction of taxes and any transaction costs is favorable to the person placing the bet.
Laying odds is reflected in the colloquial expression "[I would] dollars to doughnuts " — with which the speaker is expressing a willingness to risk losing something of value in exchange for something worthless, because winning that bet is a certainty. Bookmakers sell bets based on the odds of a specific outcome, but lay betting allows the bettor in some English-speaking countries, the "punter" to reverse roles with the bookmaker, using odds to sell the opposite outcome to the bookmaker.
In this context, "lay" is used in the sense of "layman", i. Favoured by bookmakers in the United Kingdom and Ireland and common in horse racing , fractional odds quote the net total that will be paid out to the winning bettor relative to the stake. The term "fractional odds" is something of a misnomer, especially when visually reinforced by using a slash as opposed to, e.
This fraction may be derived by subtracting 1 from the reciprocal of the chances of winning; for any odds longer than "even money," this fraction will be an improper one. Not all fractional odds are traditionally read using the lowest common denominator. Perhaps most unusual is that odds of are read as "one-hundred-to-thirty". Fractional odds are also known as British odds, UK odds,  or, in that country, traditional odds. Favoured in Continental Europe , Australia , New Zealand and Canada , decimal odds differ from fractional odds by taking into account that the bettor must first part with their stake to make a bet; the figure quoted, therefore, is the winning amount that would be paid out to the bettor.
It 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. Decimal odds are also known as European odds , digital odds or continental odds and tend to be favoured by betting exchanges because they are the easiest to work with for trading, in this case the purchase and sale of upside and downside risk. Moneyline odds are favoured by United States bookmakers and as such are sometimes called American Odds.
Moneyline refers to odds on the straight-up outcome of a game with no consideration to a point spread. To convert fractional odds to decimal, take the fractional number, convert it to decimal by doing the division, and then add 1. For example, the 4-to-1 fractional odds shown above is the same as 5 in decimal odds, while 1-to-4 would be quoted as 1. The method for converting moneyline to decimal odds depends on whether the moneyline value is positive or negative.
If the moneyline is positive, it is divided by and add 1. If the moneyline is negative, is divided by the absolute moneyline amount the minus signed is removed , and then 1 is added.

Based on this, there has a movement to attract more people to horse racing by making it more accessible to the average punter. Ten years ago, if you were going to Cheltenham, all the odds would be displayed as fractional odds.
The second difference between the formats is that fractional odds only represent winnings, and do not include the returned stake compared to decimals which do include the stake. The transition from fractional odds to decimals largely kicked off with the growing popularity of the betting exchanges such Betfair. These are hard to compute for the punter and are not a great way of showing betting odds explained.

Betting odds are applied to any event that bookmakers are taking bets on, from horse racing and football to TV specials and politics. Probability is simply how likely something is to happen. Probability is most commonly shown as a fraction by UK bookmakers, and would be two numbers separated by a forward slash e. A very simple explanation of probability would be a coin toss, in which the two possible outcomes are heads or tails.
This is how punters can use the betting odds to work out how likely bookmakers believe an outcome is to happen. Now you know odds are set out with two numbers separated by a forward slash, you can use them to work out the probability of an event happening. The method for calculating probability in percentage terms from odds is most easily explained by taking the two numbers that appear in the odds and replacing them with letters.
Now you know how to work out the probability of an event happening, you can use the betting odds to work out the potential returns if you were to bet on it. Fractional odds tell you the potential winnings in relation to the stake you place on the bet.
See below for more examples of how to read betting odds. Any odds in which the first number is bigger than the second are odds against, while any odds in which the first number is smaller than the second are odds on. Odds-on events are considered more likely to happen than not by bookmakers, and vice versa for events that odds against.
When converted into decimals, the potential winnings include the stake, so you just multiply the stake by the odds. Decimal odds are often used on betting exchanges , such as Betfair , as the user is in control of the odds rather than the bookmaker.
