How do you find the expected value of X?

In: Math and Arithmetic, Algebra, Calculus [Edit categories]

Answer:

For a discrete probability distribution, you add up x*P(x) over all possible values of x, where P(x) is the probability that the random variable X takes the value x.

For a continuous distribution you need to integrate x*P(x) with respect to x.
