Question
fx.y (x, y) = { ca-y for – y< x < y and 0 < y < 2 ] otherwise where c is a constant. a. Set-up, but do not evaluate, an integral which computes c so that fx,Y (x, y) is a probability density function. b. Set-up, but do not evaluate, integrals which compute E(X) and E(Y). c. Set-up, but do not evaluate, and integral or integrals which compute Var(X). d. Are X and Y independent? Justify your answer.
