Combinatorics, Question 2 (by T. Madas)

The Oakwood Jogging Club consists of 7 men and 6 women who go for a 5 mile run every Thursday. It is decided that a team of 8 runners would be picked at random out of the 13 runners, to represent the club at a larger meeting. Determine the proportion of teams of 8 , which have more women than men?
