How the Expected Value Calculator Works
The calculator uses the following standard formula to compute expected value:
E(X) = Σ [xᵢ × P(xᵢ)]
Where:
xᵢ = possible outcomes
P(xᵢ) = probability of each outcome
E(X) = expected value of the distribution
Once you enter your data into the fields provided, the calculator multiplies each outcome by its corresponding probability and adds them together to deliver the result instantly.
This is ideal for evaluating wagers using an expected value calculator for betting, where the goal is to determine whether a bet is +EV (positive expected value) or -EV (negative expected value).
