Consider three components such that r1 = 0.92, r2 = 0.9, r3 = 0.84.
(a) What is the system reliability if these three components are connected in series?
(b) What is the system reliability if these three components are connected in parallel?
(c) Suppose the series system in part (a) is not sufficiently reliable. If system-level redundancy is applied, what is the new value of system reliability?
(d) Suppose the series system in part (a) is not sufficiently reliable. If component-level redundancy is applied, what is the new value of system reliability?
