Suppose small aircraft arrive at a certain airport according to a Poisson process with a mean rate of 8

per hour.

a. Let be the waiting time until the 4th aircraft arrives. Identify the distribution of T, including any parameters, and find

P(T ≤ 1)

b. Let Y be the number of aircraft that arrive during a one-half hour period. Identify the distribution of Y, including any parameters, and find P(Y ≥ 3)

A small parking lot has 3 spaces (bays). Vehicles arrive randomly (according to a Poisson process) at an average rate of 6 vehicles per hour. The parking time has an exponential distribution with a mean of 30 minutes. If a vehicle arrives when the three parking spaces are occupied, it leaves immediately without waiting or returning. Find the percentage of lost customers, i.e., vehicles that arrive but cannot park due to full occupancy. Find the average number of vehicles in...

People arrive according to a Poisson process with rate λ, with each person independently being equally likely to be either a man or a woman. If a woman (man) arrives when there is at least one man (woman) waiting, then the woman (man) departs with one of the waiting men (women). If there is no member of the opposite sex waiting upon a person’s arrival, then that person waits. Let X(t) denote the number waiting at time t. Argue that...
