I have to fill out a 9 player baseball lineup, using only three players.

I have three Player A, three Player B and three Player C.

ie - one lineup might look like AAABBBCCC or AABCABCCB

My question is, what is the math formula for determining how many possible lineups there are.

And secondly, what is an easy way to list all these lineups?

Thanks -D

Hi;

Welcome to the forum.

There are

different lineups. To list them you will need a program.

Thanks. Yes, I will need a program. I may work on this. Any tips on the psuedo code?

Hi;

Go here

and enter aaabbbccc.

Easier than coding a multinomial!
