To support this statement, let’s look at the implied probabilities for each outcome of the 2015 ICC Cricket World Cup example. To understand sports betting odds, it’s important to work out how fractional odds work in practise. Some of our sportsbooks use fractional odds. If you bet 10 on a team with a price of 5/1, then a 10 winning wager would pay out 50. 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. Also known as British odds, fractional odds are quite simple to calculate. 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 odds on display never reflect the true probability or chance of an event occurring (or not occurring). It is relatively easy to predict that Man City will win against Crystal Palace, but would you be willing to risk $100 to make a profit of $61.50? 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. It is not only important to back winners, but one must do so when the odds accurately reflect the chance of winning.

Moreover, the odds displayed by different bookmakers can vary significantly, meaning that the odds displayed by a bookmaker are not always correct. Remember, odds change as the bets come in, which means probability estimations vary with time. In nine states, there is some form of pending legislation.
