Suppose that Xi, i = 1,2,3, are independent Poisson random variables with respective means λi, i = 1,2,3. Let X = X1 + X2 and Y = X2 + X3. The random vector X, Y is said to have a bivariate Poisson distribution.
(a) Find E[X] and E[Y].
(b) Find Cov(X, Y).
(c) Find the joint probability mass function P{X = i, Y = j}
