Suppose X 1 and X 2 are random variables of the discrete type which have the joint
Question:
Suppose X1 and X2 are random variables of the discrete type which have the joint pmf p(x1, x2) = (x1 + 2x2)/18, (x1, x2) = (1,1), (1,2), (2,1), (2,2), zero elsewhere. Determine the conditional mean and variance of X2, given X1 = x1, for x1 = 1 or 2. Also, compute E(3X1 − 2X2).
