15. When аn experiment is cоnducted, оne аnd оnly one of three mutuаlly exclusive events S1, S2, and S3 can occur, with P(S1) = 0.4, P(S2) = 0.5, and P(S3) = 0.1. The probabilities that a fourth event A occurs, given that event S1, S2, or S3 has occurred, are  P(A|S1) = 0.4       P(A|S2) = 0.2      P(A|S3) = 0.1  If event A is observed, find P(S1|A). (Round your answer to four decimal places.)
