Officials at the sucide prevention center know that 2% of all people who phone their hotline actually attempt sucide. A psychologist has devised a test to help identify those callers who will actually attempt sucide. She found that 80% of the people who will attempt sucide attain a positive score on this test, but only 5% of those who will not attempt sucide attain a positive score on this test. If you get a positive identification from a caller on this test, what is the probability that he would actually attempt sucide? (Hint: Set up a tree then fill in the matrix shown below with the appropriate numbers.)
