- A missile can be accidently launched in 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. (1) What is the probability of an accidental missile launch? (ii) What is the probability that A will fail if B has failed?
