A company has two machines. During any given day, each machine that is working at the beginning of the day will break down with probability 1/3. If a machine breaks down during the day, then it is sent to a repair facility and will be working on the second day after it breaks
down. (In other words, if a machine breaks down during day 3, then it will be working again at Please solve fully. DO NOT use Ai to solve. the beginning of day 5.) Letting the state of the system be the number of machines working at
the beginning of the day, formulate a transition probability matrix for this situation.
