Problem 1: Find the reliability of the system whose block diagram is shown below if R(1) = R(2) =R(3) = R(4) = R(5) = 0.9 and R(6) = R(7) =R(8) = R(9) = 0.8. Use the decomposition approach.
Problem 2:
A system has 5 components. The system will run successfully if any 3of them are functioning. Find the reliability of the system if the mission time is 8 hours. The life distribution of each component is given in the table.
