Could someone help me start this, or go in the right direction? Or show me another example. I don't know where to start.

Thank you

**MathMate**, Thursday, June 14, 2012 at 12:02amIf we have 1000 people, of which exactly two are MEN. Can we claim:

"If any two persons are picked at random, at least one of the two would be a woman."

What does that tell you?

Now back to the above problem:

"If any two persons are picked at random, at least one of the two would be a teacher."

From this information, how many people are NOT teachers?
