Your 80 year-old uncle goes to the doctor and says he has a positive test for prostate cancer. He comes to you and says, "You ar
e studying math and statistics. I heard there can be false positive tests." What is the chance I actually have prostate cancer, based on my positive test? Show how you would find this probability, and then explain to him what the answer means. (Remember, you are looking at the probability of a false positive, out of all of the total positive tests)
