A system has an overall reliability of 0.50. Calculate the overall Unreliability of the system. a. Calculate the reliability of a new system with two subsystems in series each with a b. reliability of 0.50. c. Calculate the reliability of a new system with two subsystems in parallel (back-up) each with a reliability of 0.50. d. Calculate the overall reliability of a system with two subsystems in series with the first subsystem reliability of 0.7 and second system reliability of 0.6. e. Calculate the overall reliability of a system with two subsystems in series with the first subsystem reliability of 0.6 and second system reliability of 0.70. f. Discuss the conditions of placing the 0.6 system first (or second). & Calculate the required number of inputs to produce 100 quality outputs for the systems described in part b, part c
