Medical studies have shown that 10 out of 100 adults have heart disease. When a person with heart disease is given an EKG test, a 0.9 probability exists that the test will indicate the presence of heart disease. When a person without heart disease is given an EKG test, a 0.95 probability exists that the test will indicate the person does not have heart disease. Suppose that a person arrives at an emergency room com-plaining of chest pains. An EKG is given and indicates that the person has heart dis-ease. What is the probability that the person actually has heart disease?
