+Hunter says she is itchy. There is a test for Allergy to Cats, but this test is not always right:
+For people that really do have the allergy, the test says "Yes" 80% of the time
+For people that do not have the allergy, the test says "Yes" 10% of the time ("false positive")
+If 1% of the population have the allergy, and Hunter's test says "Yes", what are the chances that Hunter really has the allergy?
