Question:
In using Bayes' rule for the presence of a disease (see Figure 6.17 and the file Bayes Rule for Disease.xlsx), we assumed that there are only two test results, positive or negative. Suppose there is another possible test result, "maybe." The 2 3 2 range B9:C10 in the file should now be replaced by a 2 3 3 range, B9:D10, for positive, maybe, and negative (in that order). Let the corresponding probabilities in row 9 be 0.85, 0.10, and 0.05, and let those in row 10 be 0.05, 0.15, and 0.80. Redo the Bayes' rule calculations with both the frequency approach and the probability approach.
