View the step-by-step solution to:

P( A 1 ) = .20, P( A 2 ) = .40, and P( A 3 ) = . P( B 1 | A 1 ) = . P( B 1 | A 2 ) = .05, and P( B 1 | A 3 ) = . Use Bayes' theorem to determine P (...

P(A1) = .20, P(A2) = .40, and P(A3) = .40.  P(B1|A1) = .25. P(B1|A2) = .05, and P(B1|A3) = .10.


Use Bayes' theorem to determine P(A3|B1). (Round your answer to 4 decimal places.)
