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 given by
Find the probability that a component of type II will have a life length in excess of 200 hours.
Reference
An electronic system has one each of two different types of components in joint operation. Let Y1 and Y2 denote the random lengths of life of the components of type I and type II, respectively. The joint density function is given by
(Measurements are in hundreds of hours.) Find P(Y1 > 1, Y2 > 1).
