If 7 girls shake hands only once how many handshakes does that make?

The question is ambiguous:
- If each girl shakes one other person's hand once, then there are seven (7) handshakes.
- If each girl shakes each other girl's hand once, then there are 7 x 6 x 0.5 = 21 handshakes (each girl x each other girl x cancelling out the doubles).
Another way to look at this one:
- If each girl shakes each of the other girl's hand once, there would be 42 shakes (each girl shakes 6 hands, times 7 girls, an assupmtion is made that each girl is not shaking her own hands, you can't tell much from the question so assuming ensues)

Prove that total number of people who lived on earth and made odd number of handshakes is always even?
If you multiply anything by 2 it always comes out even. So if people make 35 handshakes, we multiply it by 2 and we get 70 people. This will work with any different number of handshakes, odd or even.

12 members were present at a board meeting each member shook hands with all of the other members before and after the meeting how many hand shakes were there?
66. Each of the 12 members shook hands with the 11 other people. That would make 12*11 hand shakes. BUT, the A shaking B's hand is the same event as B shaking A's hand so all these handshakes are double-counted. The actual number is half that ie 33. If you are more familiar with combinatorial mathematics, the answer is the number of combinations of two obejects from 12, which is 12C2 = 12*11/(2*1)
