Random Variables, Distributions, and Expected Value
www0.gsb.columbia.eduExpectations of Random Variables 1. The expected value of a random variable is denoted by E[X]. The expected value can bethought of as the“average” value attained by therandomvariable; in fact, the expected value of a random variable is also called its mean, in which case we use the notationµ X.(µ istheGreeklettermu.) 2.

Properties of Expected values and Variance

It turns out (and we have already used) that E(r(X)) = Z 1 1 r(x)f(x)dx: This is not obvious since by de nition E(r(X)) = R 1 1 xf Y (x)dx where f Y (x) is the probability density function of Y = r(X).
