WebbThe formula is given as E(X) = μ = ∑xP(x). Here x represents values of the random variable X, P ( x) represents the corresponding probability, and symbol ∑ represents the sum of all products xP ( x ). Here we use symbol μ for the mean because it is a parameter. It represents the mean of a population. Example 4.3 WebbSign in. Probability and Statistics Formulas and Tables (1).pdf - Google Drive.
