Find the probability-that speaker B delivers speechimmediately after speaker A.7 (B5If P(A): 25, PLA)= 12 and PIB/sample space of a random experiment, then find P(A(B)2 for two events A and B İn theB) and P(B) |

Answer» 6/7 of the time A is not the last speaker, so one of the others follows him or her and it is equally likely to be any of the other 6, so the conditional probability that the one who follows A is B is 1/6. This means there’s a (6/7) * (1/6) = 1/7 chance that B follows A. Like my answer if you find it useful! |
