Suppose #7 buses arrive at a bus stop according to a Poisson process with an average of 5 buses per hour. (i.e. X = 5/hr. So 0=hr. or 12 min.) Find the probability (a) you have to wait longer than 15 minutes for a bus (b) you have to wait more than 15 minutes longer, having already been waiting for 6 minutes.
