Combinations Example 2: Two Teams + Umpire (1 of 2: No Restrictions)

Amazing!

[@leul1407]

Kinda hard to understand why we divided 630/2

[@jingcao7677]

Why wouldn't you divide by 3! since you are arranging Team A, Team B, and the umpire?

[@mulimotola44]

Because the umpire didn't affect the original count, we just multiplied by 1. So we don't need to divide by anything, because we don't need to consider him at all as part of the count.

[@davidbeckham7511]

You divide by repetitions, 2 teams of 4. 2!

[@talhafaruque7518]

I think it should have been 3 factorial instead of 2

[@varunnagp3903]

I think the lectures need to be in a permutation and not a combination(which is currently they are). 23,22,21,20 is right order to understand combinations

What if we have 16 players and had to split them into 2 teams with 2 different coaches?
