Hillside Little League has 12 teams. Each team plays each of the other team twice. How many games are played?
Answered by MathMate
This is also the handshake problem.
Use the logic of the answer to the previous post.

12 teams in total. so 1 team each plays 11 teams.
1 team plays 11 times
So 12 teams play x times
x= 11*12
x=121

11*12=132

The last two replies from above are incorrect.
It is the same logic as the handshake problem, as MathMate noted.

You are basically looking for the number of subsets of 2 elements which is
C(12,2) = 12!/(10!2!) = 66

I think that is wrong because all teams play twice so it 264 but you divide by 2 because you can't count teamA playing teamB again as Team B playing team A so, 264/2=132
