Fixed-odds betting is a form of wagering against odds offered by a bookmaker or an individual or on a bet exchange. It involves betting on an event in which there is no fluctuation on the payout. In Australia , the practice is usually known as "SP betting". It is customary with fixed-odds gambling to know the odds at the time of the placement of the wager the "live price" , but the category also includes wagers whose price is determined only when the race or game starts the " starting prices ".
In the more usual case of an imbalanced book, the bookmaker may have to pay out more winnings than what is staked or may earn more than mathematically expected. An imbalanced book may arise since there is no way for a bookmaker to know the true probabilities for the outcome of competitions left to human effort or to predict the bets that will be attracted from others by fixed odds compiled on the basis personal view and knowledge.
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.
