**Reiny**, Wednesday, February 10, 2010 at 12:31pmI agree with your answers to the first 4 questions.

for the last:

Each of the 10 players plays against the other 9.

So that is 90

But...

it includes A vs B and B vs A, which is the same game, so we divide the above by 2

so there are 45 games.

Or ... short-cut way

choose pairs of 2's from 10

= C(10,2) = 45
