An accident occurs when both fault event A and fault event B occur. The equation for joint probability of two fault events under any circumstances is given by:

P(A&B) = P(A|B) × P(B) where P(A|B) means the probability of fault A given that fault B has occurred. If the occurrence of fault B does not affect the probability of the occurrence of fault A, the probability of an accident, when P(A) = .1 and P(B) = .05, is given by:
