Users arrive at a website according to a Poisson process with the rate of 10 users per hour. We are examining the arrivals of the users starting from 8am on Monday. Let . I denote the duration till the arrival of the 3rd user, measured in minutes. . N denote the number of customers arriving between 8:00am and 8:20am. 1. What is the expected value of T? ET= 2. What is the probability that N = 3? P(N = 3) = 3. Knowing N = 3, what is the probability that T
