It is known that steroids give users an advantage in athletic contests, but it is also known that steroid use is banned in athletics.

As a result, a steroid testing program has been instituted and athletes are randomly tested. The test procedures are believed to be equally effective between users and non-users. 90% of the athletes affected by this program are clean. The probability that the next athlete will be a user and fail the test is 0.098. Given that an athlete is a user, what is probability the test is accurate?
