A common test for AIDS is called the ELISA (enzyme-linked immunosorbent assay) test. Among 1 million people who are given the ELISA test, we can expect results similar to those given in the following table:
If one of these 1 million people is selected randomly, find the following probabilities: (a) \(P\left(B_{1}\right)\), (b) \(P\left(A_{1}\right)\), (c) \(P\left(A_{1} \mid B_{2}\right)\), (d) \(P\left(B_{1} \mid A_{1}\right)\). (e) In words, what do parts (c) and (d) say?
