(а) Prоve thаt, cоnditiоnаl upon the fact that exactly one event occurs in a Poisson process by time s, the time T that the event occurs has a uniform distribution. (b) Suppose busses arrive at a bus stop according to a Poisson process with rate 3 busses per hour, determine the probability that 4 busses arrive between 1:00 pm and 2:30 pm, and 3 busses arrive between 3:00 pm and 3:45 pm. (c) Determine the probability that the fifth bus in part (b) arrives within 120 minutes (you may leave your answer in the form of an integral.)
