  1. There are lots of solutions to this problem. One of them is
    H=11
    T=7
    B=0
    H&T=2
    H&B=1
    T&B=1
    H&T&B=2
    So, 4 play exactly two games.

    But there is so much unspecified, the numbers can be juggled in many ways.
    Draw a Venn diagram and fill in the center value of 2, and you can see other solutions.
