9. Suppose X and Y are random variables with joint density function f(x, y) = 0.08 e^-(0.4x+0.2y

Name: 9. Suppose X and Y are random variables with joint density function f(x, y) = 0.08 e^-(0.4x+0.2y) if x >= 0, y >= 0, 0 otherwise (a) Verify that f is indeed a joint density function. (b) Find the probabilities: (i) P(Y >= 1), (ii) P(X <= 2, Y >= 4). (c) Find the expected values of X and Y.
