Answer.....

A repairable system contains three components. Components 2 and 3 are in parallel and both are required for subsystem success. Component 1 is in series with the parallel combination of 2 and 3. If the system fails, no further failures can occur until the system is placed back in service. >, =0.3 f/ yr: 12 =0.5 f/ yr. As = 3.5 f / yr and H1 = M2 = M3 = 50 r/yr. a. Calculate the probability of the system being found in the failed state b. What is the reliability of the system for a 750 hour mission
