Implied Probability is also useful when evaluating a bet or checking how likely an outcome is. Decimals quote the potential return should the bet succeed, relative to the stake. Used mostly in the United Kingdom and Ireland, fractions quote the potential profit should the bet succeed, relative to the stake. Odds correlate to probability. The moneyline is one of the most common bets.
This is a straight-up bet. All you need to do is pick the winning team. The odds would look something like this:. The amount that is set by the oddsmakers is based on how they foresee a game unfolding from a scoring perspective. If you believe the combined score for both teams will be points or more, you would bet the OVER. For point spread bets , the oddsmaker adjusts the line so that the underdog gets an advantage.
You would enter in the American Odds section if you believe Boston will cover or enter in the American Odds section if you think New York will cover. If you bet on the Knicks, then they would have to win by four points or more. If you bet on the Celtics, they would need to win outright or lose by three points or less for you to win your bet.

The first thing to understand is that there are three distinct types of odds: fractional, decimal, and American moneyline.
The various types are represent different formats to present probabilities, which are also used by bookmakers, and one type can be converted into another. Once the implied probability for an outcome is known, decisions can be made regarding whether or not to place a bet or wager. Although odds require seemingly complicated calculations, the concept is easier to understand once you fully grasp the three types of odds and how to convert the numbers into implied probabilities.
There are tools available to make conversions between the three types of odds. Many online betting websites offer an option to display the odds in the preferred format. The table below can help convert odds with pen and paper, for those interested in doing the calculations by hand. Converting odds to their implied probabilities is perhaps the most interesting part. The general rule for the conversion of any type of odds into an implied probability can be expressed as a formula:.
As shown, the formula divides the stake amount wagered by the total payout to get the implied probability of an outcome. Plug the numbers into the formula, which is a simple matter of dividing 8 by 13 in this example, and the implied probability equals The higher the number, the greater the probability of the outcome.
Using an example of decimal odds, a candidate has 2. If so, the implied probability is Therefore, the implied probability equals Remember, odds change as the bets come in, which means probability estimations vary with time.
Moreover, the odds displayed by different bookmakers can vary significantly, meaning that the odds displayed by a bookmaker are not always correct. It is not only important to back winners, but one must do so when the odds accurately reflect the chance of winning. 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.
Note that you will also receive back your initial wager if you make a winning bet. 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.
That is because multiple wins are likely to yield small stakes, for which you need to play more, and the more you play, the more likely you will eventually bear the brunt of occasional and substantial losses.
