I used a Venn Diagram, like this but without words http://www.learnnc.org/media/glossary…

I labelled each circle a group and put in the numbers where people crossed over, so where the Volley Ball and Tennis group overlapped, I put in 4 crosses. I did this for each coupling.

With the overlaps done, it was simply counting how many the group was lacking, and putting them in their category then counting all of them up.

10 on volleyball, 9 on track, 10 on tennis

Volleyball(10) | Tennis (10) | Track (9) |
————————————————————-
Volley| 10 | 4 (6) | 3 (6) |
Tennis| 0 | 10 | 3 (3) |
————————————————————
10 + 6 + 3 = 19

so much easier when you make a chart
