Calls arrive at a switchboard as a Poisson process with rate λ = 4 per minute. Find the probabilities that, with respect to any fixed origin in time, the twelfth subsequent call arrives: (a) before two minutes have elapsed [hint: consider the distribution of the number of calls arriving in these two minutes], (b) after three minutes and before five minutes have elapsed.
