What is Expected Value?

Expected Value (EV) is a mathematical concept that helps bettors determine whether a bet has positive or negative value in the long run. A positive EV means that, on average, you can expect to make money from the bet over time. A negative EV means you can expect to lose money over time.

The formula for Expected Value is: EV = (Probability of Winning × Potential Profit) - (Probability of Losing × Stake)

This is your assessment of the true probability of the outcome occurring.
