Suppose that we are waiting for two events a and b to occur. x = the time until event a occurs and y = the time until event b occurs. we model the probability distribution of the two times with the joint density
f(x, y) = e^(−2x− y/2) [3/4 e^−x + e^−y/2 ]
for x > 0 and y > 0.
(a) what is the probability that x < 1 but y > 1?
(b) what is the probability that x > y ?
