3. An electronic system has one each of two different types of components in joint operation. Let Y, and Y, denote the random lengths of life of the components of type I and type II, respectively. The joint density function is given by 1 f(y1. Y2) = 0, ,Y1 > 0, y2 > 0 elsewhere a) Find P(Y, > 1, Y2 > 1) b) Are Y, and Y2 independent? c) What is the marginal distribution of Y,
