WebJun 9, 2024 · A probability distribution is a mathematical function that describes the probability of different possible values of a variable. Probability distributions are often … 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 ...
