Let X and Y be two continuous random variables with the joint probability distribution function: f(x, y) = {* + Y. fx + y, 0<x < 1 and 0 < y < 1 otherwise Suppose that the marginal functions are given by: g(x) = 0) x + 0<x<1 and h(y) = Įy+ 0<y<1 otherwise otherwise If E(XY) = ÷ Then Var(X – Y – 9) is equal to: 3' 131/144 None of these O 24/144 O 20/144
