Venn diagrams with 3 circles

The overlapping region of these two circles is shown below. We already have the 7 students that play all three sports in this region. Therefore we only need 3 more students who play basketball and tennis but do not play football to make the total of this region add up to The next overlapping region of two circles is those that play basketball and football.
