Expected Values

Expected value is a concept in probability theory that represents the average outcome of a random variable over an infinite number of trials.

It is calculated by multiplying each possible outcome by its probability of occurring, and then summing these products. Expected value is a key concept in statistical inference, machine learning, and decision theory.
