Mark has just became a historian at one of the National Museums in New York. Out of curiosity, he partnered with 5 other museum employees at 5 other museums and conducted research to find out how many men versus women visited the museums last month. What is the probability that a visitor, chosen at random, is a man who visited Museum 3? Enter your answer as a percent to 2 decimal places, such as: 42.53%
