Assume that the airline reservation system has two computers, and they can be working in parallel (can be working at the same time). Each computer can break down with probability p. Repairing each computer takes 2 days, and 2 computers cannot be repaired in parallel. Breakdown and repair cannot occur for the same computer on the same day.
a. Determine states and the transition probability matrix. Let q=1-p. Solve for the stationary distribution and determine availability.
