On average, based on past records, a Forklift will have a failure rate once every 7000 hours of drive time. Mechanical failure of Forklifts constitutes a Poisson process. (a) If a Forklift is scheduled for inspection and maintenance after every 2500 drive hours, what is the probability of mechanical failure of a Forklift between inspections? (b) In a fleet of 20 Forklifts of the same type, what is the probability that not more than two (S 2) will have mechanical failure within the above scheduled inspection/maintenance interval? Assume that failure between Forklifts is statistically independent.

A barbershop is operated by one barber and has a space capacity to accommodate for a total of 6 customers (including the one in service). If a customer comes to this shop and finds it full, he goes to other shops. Customers arrive according to Poisson distribution at a rate of 4.1 customers per hour. The barber’s service time is exponential and he can serve at a rate of 7.1 customers per hour. a. What is the probability that the barber is free? Answer = Answer b. What is the expected number of people in the system? Answer = Answer c. What is the expected waiting time in the queue? Answer = Answerhours. (hint: use effective arrival rate)
