Let X and Y be independent random variables, X~ Poisson (y) and Y~ Poisson (X); that is, for every pair of integers (i, j) such that 0 ≤ i and 0 ≤ j, P((X= i) n (Y = j)) = P(X= i) × P(Y = j). (d) For k = S, let g: S (-∞, +∞) be function defined by g(k) = E(Tk), where for m≥ 0, T is the random variable such that P(T₁ = m) = P(X = m|X + Y = k). Derive a simple algebraic expression for g(k).
