A facility of 3 identical machines is sharing a single repair person. The time to repair a failed machine is exponentially distributed with mean 1/3. A machine once operational, fails after a time that is exponentially distributed with mean 1/4. All failure and repair times are independent. (1). Find the steady-state probability that there is no operational machine. (2). Find the expected number of operational machines, in steady-state.
