Equation to find probability

WebDefinition \(\PageIndex{1}\) The probability mass function (pmf) (or frequency function) of a discrete random variable \(X\) assigns probabilities to the possible values of the random variable.More specifically, if \(x_1, x_2, \ldots\) denote the possible values of a random variable \(X\), then the probability mass function is denoted as \(p\) and we write WebSep 10, 2024 · The probability of getting Heads is 1 2, as is the probability of getting Tails. The expected value of the game is. ( 1 2 × .25) + ( 1 2 × ( − .25)) = 0. Thus, you would expect an average payoff of $ 0, if you were to play the game several times. Note, the expected value is not necessarily the actual value of playing the game.
