Two events A and B of an experiment are such that every trial gives exactly one of A or B (they cover all outcomes and never both happen). In 600 trials, A happened 216 times. Find the empirical probability of event B.

Question

Accepted Answer

0.64. Since A and B cover all outcomes with no overlap, P(B) = 1 - P(A) = 1 - 216/600 = 384/600 = 0.64.
