The document describes a system with 4 modules connected in series. Module A and B are connected in series with reliabilities of 0.995 and 0.99. Module C consists of 3 components in parallel with reliabilities of 0.95, 0.98, and 0.98. Module D has 2 components in parallel with reliabilities of 0.999 and 0.965. The document asks to draw the configuration and compute the system reliability.
