Problem 5.112

In Exercise 5.18, Y1 and Y2 denoted the lengths of life, in hundreds of hours, for components of types I and II, respectively, in an electronic system. The joint density of Y1 and Y2 is f (y1, y2) = (1/8)y1e(y1+y2)/2, y1 > 0, y2 > 0, 0, elsewhere. The cost C of replacing the two components depends upon their length of life at failure and is given by C = 50 + 2Y1 + 4Y2. Find E(C) and V(C).
