There are 14 players on the softball team, we don't care about the order but we can't repeat a player. So we are going to use combinations, we don't care in what order the players are placed - we only care that they are in the batting order somewhere.
c = n! / (x! *( n -x))
Where n = 14 and x=3
Replace and solve
c = 14! / (3! * ( 14 -3)!)
c = 14! / (3! * ( 14 -3)!) = 364 ways
