The previous problems were: A basketball team is made up of 5 players. If there are 20 players at the gym, how many ways can they form one basketball team? Suppose 20 players want to divide themselves into a total of four teams. How many ways can they do so? How many ways can four Basketball teams split into two games?

The problem I need help with is: Putting the previous parts together, how many ways can 20 players divide themselves up to play two games of basketball?

I tried to put my answers to the previous ones but it would not let me..It says that I put other people's answers.

Thank you!
