The exponential distribution is frequently ap- plied to the waiting times between successes in a pois- son process. if the number of calls received per hour by a telephone answering service is a poisson random variable with parameter λ = 6, we know that the time, in hours, between successive calls has an exponential distribution with parameter β =1/6. what is the prob- ability of waiting more than 15 minutes between any two successive calls?
