Lecture 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. If X ≥ Y, then E[X] ≥ E[Y] Now let’s think about ...

Two Types of Random Variables A discrete random variable: Values constitute a finite or countably infinite set A continuous random variable: 1. Its set of possible values is the set of real numbers R, one interval, or a disjoint union of intervals on the real line (e.g., [0, 10] ∪ [20, 30]). 2.
