Suppose you wanted to evaluate the performance of the three judges in Smallville, Texas: Judge Adams, Judge Brown, and Judge Carter. Over a three-year period in Smallville, Judge Adams saw 23% of the cases, Judge Brown saw 30% of the cases, and Judge Carter saw the remainder of the cases. 4% of Judge Adams’ cases were appealed, 6% of Judge Brown’s cases were appealed, and 8% of Judge Carter’s cases were appealed.
3) Given a case from this three-year period was not appealed, what is the probability the judge in the case was not Judge Brown?
