9) Probability that the system will work = P(A or B working) and P(C working) and P(D or E working)
= [1 - P(both A and B not working)] x P(C working) x [1 - P(both D and E not working)]
= [1 - (1-0.9)(1-0.9)] x 0.95 x [1 - (1-0.8)(1-0.9)]
= [1 - 0.1x0.1] x 0.95 x [1 - 0.2x0.1]
= 0.99 x 0.95 x 0.98
= 0.9217
