www.stat.cmu.eduLecture 6: Discrete Random Variables 19 September 2005 1 Expectation The expectation of a random variable is its average value, with weights in the average given by the probability distribution E[X] = X x Pr(X = x)x If c is a constant, E[c] = c. If a and b are constants, E[aX +b] = aE[X]+b.
