Customers arrive at a common queue at the coffee station with two identical coffee machines in a busy mall at the rate of 48 per hour, following Poisson distribution. Each customer mixes his or her specialty coffee taking 2 minutes on an average following an exponential process. What is the expected number of customers in the system at this coffee station?

Step 1
The arrival rate (Ī») is given as 48 customers per hour. The service rate (Ī¼) can be calculated from the given average service time. Since each customer takes 2 minutes on average to mix their coffee, the number of customers that one machine can serve in an hour Show moreā¦

Customers checking out at Food Tiger arrive in a single-line queue served by two cashiers at a rate of eight per hour according to a Poisson distribution. Each cashier processes customers at a rate of eight per hour according to an exponential distribution. If, on average, customers spend 30 minutes shopping before getting in the check-out line, what is the average time a customer spends in the store? What is the average number of customers waiting for service in the checkout line? What is the probability that a customer must wait? What assumption did you make to answer this question?

One pharmacist works filling orders for medications. 10 orders come in per hour. Filling the orders takes an average of 4 minutes each. Assume that orders and fills have the Poisson distribution (so service times have the exponential distribution). Calculate; a. The probability of zero person in the system b. The average number of customers waiting or being served c. The average number of customers waiting in the queue d. The average time in system e. The average time in queue

Refer to Exercise $3.122 .$ Assume that arrivals occur according to a Poisson process with an average of seven per hour. What is the probability that exactly two customers arrive in the twohour period of time between a. 2: 00 P.M. and 4: 00 P.M. (one continuous two-hour period)? b. 1: 00 P.M. and 2: 00 p.M. or between 3: 00 p.M. and 4: 00 P.M. (two separate one-hour periods that total two hours)?
