The computer center at Rock-bottom University has been experiencing computer downtime. Let us assume that the trials of an associated Markov process are defined as one-hour periods and that the probability of the system being in a running state or a down state is based on the state of the system in the previous period. Historical data show the following transition probabilities:

                                

  a. If the system is initially running, what is the probability of the system being down in the next hour of operation?
  b. What are the steady-state probabilities of the system being in the running state and in the down state?
