Question

A missile can be accidentally launched if two relays A and B both
have failed. The probabilities of A and B failing are known to be 0.01
and 0.03 respectively. It is also known that B is more likely to fail
(probability 0.06) if A has failed.
(i) What is the probability of an accidental missile launch?
(ii) What is the probability that A will fail if B has failed?
(iii) Are the events “A fails” and “B fails” statistically
independent
