Four components A$,$ B$,$ C$,$ and D are placed in series to make a subassembly in a circuit board. The reliabilities of A$,$ B$,$ C$,$ and D are $0\mathrm{.}93,0\mathrm{.}88,0\mathrm{.}95,$ and $0\mathrm{.}92,$ respectively. Find the reliability of the subassembly. What will be the reliability if all four components are placed in parallel? Analyze which is the most appropriate configuration, whether series or parallel, in this case and justify your reasoning.
