Let the discrete random variables Y1 and Y2 have the joint probability function p(y1
Chapter 5, Problem 5.93(choose chapter or problem)
Let the discrete random variables Y1 and Y2 have the joint probability function p(y1, y2) = 1/3, for (y1, y2) = (1, 0), (0, 1), (1, 0). Find Cov(Y1, Y2). Notice that Y1 and Y2 are dependent. (Why?) This is another example of uncorrelated random variables that are not independent.
