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 h
ome 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
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.
