Question 1
1.
At a movie theater customers arrive at the rate of 1 every minute. The ticket seller
averages 30 seconds per customer.
a.
What is the average customer time in the system?
b.
What is the average customer time in line?
c.
What is the average number of customers in line?
d.
What is the probability that the ticket taker is idle?
a. L
s
= 1/(21) = 1 customer
W
s
= 1/1 = 1 minute  the average customer time in the system
b. L
q
= 1
2
/2(21) = 1/2 = 0.5 customers
W
q
= 0.5/1 = 0.5 minute = 30 seconds  the average customer time in line
c. L
q
= 1
2
/2(21) = 0.5 customers  the average number of customers in line
d. The probability that the ticket taker is idle is the same as the probability that there is no
customers in the system therefore:
P
0
= (11/2) = 1/2 = 0.5 = 50%
