Plain-text version
For events A and B, it has been reported by an investigator that probabilities P(A) = 0.6, P(B) = 0.4, and conditional probability P(B|A) = 0.75. Then what can be said about conditional probability P(A|B)? (A) P(A|B) = P(A)/P(B|A) = 0.8 (B) P(A|B) = P(B)/P(A) = 2/3 (C) P(A|B) = 1 - P(B|A) = 0.25 (D) The reported data on probabilities is inconsistent
