Note: The exercise, as posted, is poorly phrased. I am fairly certain that the previous reply is making the assumption that the exercise statement is meant to express the following:

"A company with 50 employees has three standing committees, being finance, program, and planning. The finance committee has 25 members; program has 18 members; planning has 20. Ten employees are on both the finance and program committees; 11 are on both the program and planning committees, with 5 of these being also on the finance committee; and 12 employees are on the finance and planning committees."

I would make the same assumption about the meaning, but you might want to state in your homework that this is the assumption that you are making, just in case. :wink:
