A diagnostic test is designed to detect a cancer precursor enzyme that exists in 1 of every 1000 people. The test falsely identifies the presence of the enzyme in 20 out of 1000 people who actually do not have the enzyme. What is the percent chance that a person identified as having the enzyme actually does have the enzyme?
