Question

 It is estimated that approximately 8.46% Americans are afflicted with diabetes. Suppose that a certain diagnostic evaluation for diabetes will correctly diagnose 96.5% of all adults over 4040 with diabetes as having the disease and incorrectly diagnoses 4% of all adults over 4040 without diabetes as having the disease.

    a) Find the probability that a randomly selected adult over 4040 does not have diabetes, and is diagnosed as having diabetes (such diagnoses are called "false positives").

            

    b) Find the probability that a randomly selected adult of 4040 is diagnosed as not having diabetes.

            

    c) Find the probability that a randomly selected adult over 4040 actually has diabetes, given that he/she is diagnosed as not having diabetes (such diagnoses are called "false negatives").
