- Suppose the customers arrive at a Poisson rate of on eper every 12 minutes, and that the service time is exponential at a rate of one service per 8 minutes. What are the average number of customers in the system(L) and the average time a customer spends in the system(W)?A car servicing station has 2 bays where service can be offered simultaneously. Because of space limitation, only 4 cars are accepted for servicing. The arrival pattern is Poisson with 12 cars per day. The service time in both the bays is exponentially distributed with µ = 8 cars per day per bay. Find the average number of cars in the service station, the average number of cars waiting for service and the average time a car spends in the system.A file consisting of X packets is sent over the network to an end user

- Please calculate abd show all working out.A car wash has a space that can only accommodate 3 cars and 2 lanes for washing cars. Each lane can only accommodate 1 car. Cars come to this place according to the Poisson process, at an average rate of 30 cars per hour, but avoid entering this place when it is full. This work and cleaning is done manually (by manpower), and appears to follow an exponential distribution Under normal circumstances, each lane takes an average of 5 minutes to service a car. However, if there are 2 cars waiting to be served, the service will be accelerated, thus shortening the average service time to 4 minutes. Determine (a) the number of cars expected to be in this car wash and (b) the time a car will spend in this place if it does not shy away from entering.If 3% of all cars fail the emissions inspection, find the probability that in a sampleof 90 cars, 3 will fail. Use the Poisson approximation
