WEBFeb 7, 2024 · Have a look at the expected value formula: \small E (X) = x_1 \cdot P (x_1) + \ldots + x_n \cdot P (x_n) E (X) = x1 ⋅ P (x1) + … + xn ⋅ P (xn) where P (x_i) P (xi) is the probability of value x_i xi occurring ( i = 1, \ldots, n i = 1,…,n) and n n the number of all all possible values assumed by our random variable.

WEBWhat is the Expected Value Formula? The formula for expected value \((EV)\) is: $$ E(X) = \mu_x = x_{1}P(x_1) + x_{2}P(x_2) + … + x_{n}P(x_n) $$ $$ E(X) = \mu_x = \sum_{i=1}^{n} x_i * P(x_i) $$ where; \(E(X)\) is referred to as the expected value of the random variable \((X)\) \(\mu_x\) is indicated as the mean of \(X\)
