Mean of the random variable calculator
WebMay 31, 2024 · A discrete random variable has a discrete uniform distribution if each value of the random variable is equally likely and the values of the random variable are uniformly distributed throughout some specified interval. Use this discrete uniform distribution calculator to find probability and cumulative probabilities. Calculator WebTo 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 = ∑xP(x). Here x represents values of the random variable X, P ( x) represents the corresponding probability, and symbol ∑ represents the ...
