Hi,
I'm wondering if there's any way to use a double-set matrix, instead of a Venn Diagram, to solve this problem:
How many people are directors of both company K and company R?
1) There were 17 directors present at a joint meeting of the directors of company K and company R, and no directors were absent
2) Company K has 12 directors and company R has 8 directors
