Question description

A student studing for a master's degree in sports mamanagem is working on a thesis about the prevalence of women's college sports since title IX mandated equal access to women.  He compiles data on 119 schools with football teams that competed in the NCAA FBS & finds that 69 have a women's golf team, 63 have a field hockey team and 83 have a women's swimming team.  There are 28 schools that field teams in all three sports, 46 have a swimming and field hockey teams, and 47 have a women's golf and field hockey teams.

my issue is I don't even know where to begin

a) how many schools have a women's golf team, but no women's swimming or field hockey team.. seems logical all of the schools seem to have at least one or the other.

b) what percentage of teams have at least two of the three sports? I say 100% all of them have at least 2 of the three sports mentioned

c) if you pick on of the schools in the study at random, what's the percent chance that it has none of the 3 sports? 0% because they all have at least one of the sports..


im confused
