... Let Z = 3X − Y . Find the mean and variance of Z Let W = X 2 + Y 2 . Find the mean and variance of W 3. Let X and Y be independent random variables. Each of them has a geometric distribution with E[X] = 2 and E[Y ] = 4. (a) Find the joint p.m.f. of X and Y . (b) Compute the probability that X + Y ≤ ...
