A steroid detection test is 87% effective at detecting steroid use, meaning that the probability of a user testing positive is 0.87. Unfo it has a false positive rate of 8%, meaning the the probability of of a nonuser testing positive is 0.08. A large university estimates tha- 18% of its athletes use steroids. The university track captain tests positive for steroids, yet he claims he does not use them. What are chances that he is telling the truth? (Enter the probability as a decimal rounded to four decimal places.)
