A steroid detection test is 86% effective at detecting steroid use, meaning that the probability of a user testing positive is 0.86. Unfortunately, it has a false positive rate of 12%, meaning the the probabilisy of of a nonuser testing positive is 0.12. A large university estimates that about 10% of its athletes use steroids. The universitys quarterback tests positive for steroids, yet he claims he does not use them. What are the chances that he is telling the truth? (Enter the probability as a decimal rounded to four decimal places.)
