9. Player A and B Play a game in which each player has three coins [25p, 50p and 100p
(one rupee)]. Each of them selects a coin without the knowledge of the other person. If
the sum of the values of the coins is an even number, A wins B?s coin. If that sum is an
odd number, B wins A?s coin.
a) Develop a payoff matrix with respect to player A.
b) Find the optimal strategies for the players. [10]
10. Customers arrive at a hair dressing shop according to Poisson distribution. The average
time between successive arrivals is 6 minutes. There are three hair dressers, all of same
efficiency. The service time of the customers is exponentially distributed with a mean
equal to 10 minutes per customer. Find (a) the expected number of customers in the shop
(b) the expected time a customer spends in the shop (c) the average time a customer has
to wait in the queue (d) the expected number of hairdressers idle. [10]

11. A TV repairman finds that the time spent on his jobs has an exponential distribution with
a mean 30 minutes. If he repairs sets on the first-come-first-served basis and if the arrival
of sets is with an average rate of 10 per 8 hour day, what is repairman?s expected idle
time each day? Also obtain average number of units in the system. [10]
