The joint distribution for the length of life of two different types of componentgs operating in a system was given in by f(y1, y1) = (1/8)y1 exp(−(y1 + y2)/2), y1 > 0, y2 > 0, 0 elsewhere. The relative efficiency of teh two types of components is measured by U = Y1/Y1 . Find the probability density function for U
