X1, X2 = 0 - Suppose an auto company has three plants in cities A, B and C and two major distribution centers
in D and E. The capacities of the three plants during the next quarter are 1000, 1500 and
1200 cars. The quarterly demands of the two distribution centers are 2300 and 1400 cars. The
transportation costs (which depend on the mileage, transport company etc.) between the plants--- Content provided by FirstRanker.com ---
and the distribution centers is as follows:--- Content provided by FirstRanker.com ---

- Each airline passenger and his or her luggage must be checked to determine whether he or she is
carrying weapons onto the plane. Suppose that at Gotham City Airport, an average of
10 passengers per minute arrive (inter arrival times are exponential). To check passengers for--- Content provided by FirstRanker.com ---
weapons, the airport must have a checkpoint consisting of a metal detector and baggage X-Ray
machine. Whenever a checkpoint is in operation, two employees are required. A checkpoint can
check an average of 12 passengers per minute (the time to check a passenger is exponential).
Under the assumption that the airport has only one checkpoint, answer the questions:- What is the probability that a passenger will have to wait before being checked for weapons?
- On the average how many passengers are waiting in line to enter the checkpoint?
- On the average, how long will a passenger spend at the checkpoint?
