The time between successive arrivals of buses may be modelled by a distribution whose density function is f(x) = 20² (x+0)³' x > 0. * If I arrive at the bus stop just as one bus is leaving, what is the probability that I have to wait at least x minutes for the next one? * Suppose that I have already been waiting for c minutes, where c < x. Find the probability that I have to wait at least x minutes altogether.
