function given by 3x4. x 21, Sx(x) = 0, otherwise. A new random variable Y is defined by the relation Y X1. Find the cumulative distribution function of Y, and hence derive its probability density function. Verify that, for X and Y as given above, E(XY) # E(X) E(Y), and explain why this result holds in this particular example.
