Expected Value (EV) in sports betting is a statistical measure that estimates the average outcome of a bet over time, helping bettors determine if a wager is likely to be profitable. To calculate EV, you multiply the probability of winning by the amount won per bet, then subtract the probability of losing multiplied by the amount lost. For example, if you place a bet on a team with a high chance of winning and favorable odds, you would first identify the potential returns from a win and the losses if the bet does not succeed.
