The time between arrival of CAT buses follows an exponential distribution, with a mean of 20 minutes (I hear you it's long). • What is the probability that exactly four buses will arrive during the next 2 hours? • That at least two buses will arrive during the next 2 hours? • What is the expected number of buses that will arrive during the next 3 hours? • A bus has just arrived. What is the probability that it will be between 15 and 35 minutes before the next bus arrives?
