What is expected value for dummies?

In statistics and probability analysis, the expected value is calculated by multiplying each of the possible outcomes by the likelihood each outcome will occur and then summing all of those values. By calculating expected values, investors can choose the scenario most likely to give the desired outcome.

How do you bet on expected value?

The formula is: Expected Value = (Winning implied probability % * profit if bet won) – (Losing implied probability % * stake). If the calculated number is positive, that means the bet has a positive expected value and if we simulated that event an infinite number of times you would always net a profit.

What is expected value example questions?

The expected value is often denoted just by E. Example: Suppose for some game, p(win) = 2/6; p(lose) = 4/6 If you lose, you pay $1; if you win other player pays you $D What should D be if the game is to be fair? The game costs $2 to play.

How does expected value work?

To find the expected value, E(X), or mean μ of a discrete random variable X, simply multiply each value of the random variable by its probability and add the products. The formula is given as E ( X ) = μ = ∑ x P ( x ) .

What is expected value examples with answers?
