Problem 4
Consider the system of components connected as depicted below. The system can be thought
of as being comprised of two subsystems: one with components A and B, and the other with
components C and D. Components A and B are connected in parallel, therefore that subsystem
works iff either A or B works. Since C and D are connected in series, that subsystem works iff
both C and D work. Components work independent of each other (that is, operation/failure of
one component doesn't influence the operation/failure of another). If event A is defined as
"component A works" and so on, then P(A) = 0.9, P(B) = 0.88, P(C) = 0.94, and P(D) =
0.98.
a. Calculate P(system works) as a function of only the P(-) notation - no numbers.
b. Calculate the quantity for P(system works).
