Transcribed Image Text:roblem #8: Consider the system of independent components connected as in the figure below. The system works only if there
is a path of functional components from left to right. Components 1 and 2 are connected in parallel, so that
subsystem works if and only if either 1 or 2 works. Since 3 and 4 are connected in series, that subsystem works if
and only if both 3 and 4 work. Suppose that P(1 works) = 0.72, P(2 works) = 0.73, P(3 works) = 0.85, and
P(4 works) = 0.86, and these events are mutually independent.
