wo components of a minicomputer have the following joint pdf for their useful lifetimes X and xe¯«1+y) x2 0 and y > 0 f(x, y) otherwise (a) What is the probability that the lifetime X of the first component exceeds 3? (b) What are the marginal pdf's of X and Y? Are the two lifetimes independent? Explain. (c) What is the probability that the lifetime of at least one component exceed: 3? (d) Find E(X) and E(Y)
