Question

A man wants to test for diabetes. His family history shows that the probability of getting diabetes is 0.6. He decides to do a home test to check whether he has the disease. The test has an 85% accuracy rate. What is the probability before the test is taken that the patient has diabetes? 0.08 0.09 0.51 0.60

Answer 1

So,

The probability of the man having diabetes is 0.6 or 60%.  Because we are figuring the probability BEFORE the test is taken that he has the disease, we can disregard the test and its accuracy rate.  That rate is 60%, the probability of him having diabetes.

The correct option is D.
