A computer system for modelling air traffic flow of a hub airport that flights are routed though assumes that fights pass through the hub airport according to a Poisson process with rate X = 20 per hour and that jumbo passenger jets (JPJs) pass through according to an independent Poisson process with rate λJPJ per hour. Telephone calls arrive at a helpline according to a Poisson process with rate \ = 25 calls per hour. Explain why the probability of the following two events: • There are no calls for 10 minutes and there are no calls in a 20 minute period, given that there have been no calls in the first 10 of those minutes are the same and calculate this probability.
