a) illustrate this information on a Venn diagram
b) find the number of woman who lay volleyball

Answer 1

Sketch your three intersecting circles, V, B, and T
place 20, 10 and 6 in the "only" part of the circles.
Place 4 in the intersection of all circles.
Place x in the remaining parts of the circle.
Add up all the parts:
x + x + x + 4 + 20 + 10 + 6 = 70
3x + 40 = 70
3x = 30
x = 10

Now you know all parts of the different circles
