Suppose X and Y are random variables with joint density function. So.1e-(0.5x+0.2y) if x 2 0, y 2 0 lo f(x, y) = %3D otherwise (a) Is fa joint density function? Yes O No (b) Find P(Y 2 6). (Round your answer to four decimal places.) Find P(X S 5, YS 7). (Round your answer to four decimal places.) (c) Find the expected value of X. Find the expected value of Y.
