Determine the probability event A in the fault tree of Fig. 3 below if all the basic events are statically independent and mutually exclusive of one another. The probabilities of the basic event are estimated as follows:
P(D)= 0.05
P(H) = 0.12
P(L) = 0.05
P(F) = 0.15
P(I) = 0.10
P(G) = 0.20
P(K) = 0.05
