You can put this solution on YOUR website! There are 4 infield positions on a baseball team. There are 12 players. How many ways can these players play the 4 positions?
-------------------
You need to know how many groups of 4 there are when you have 12 people.
To count groups you need to count combinations.
12C4 = [12*11*10*9]/[1*2*3*4]=495 ways
----------
Then you need to determine who plays 1st, who plays 2nd, who plays 3rd and
who catches. That requires that you count the permutations in each group.
4P4=4!=4*3*2*1=24
--------------
Total # of ways = 24*495=11,880 ways they can fill the infield positions.
-----------
