First of all, does order matter? Does it matter what order you do these chores in?

If order does not matter, use a combination! When order matters, use a permutation.

You have 6 chores to start with, you do any one of them, then you have 5 chores. you do another one of them, then you have 4 chores. The whole way down you can also do them in any order so it ends up being: 6! = 720 total ways.

That's actually a permutation, but I'm trying to figure out why order matters then...
blurbendy
  • blurbendy
I think it's because the chores themselves are different. Like taking out the trash in NOT the same as washing the dishes.
blurbendy
  • blurbendy
If it was just one chore, like wash the dishes 6 times it would be a combination. Your two numbers would be 6. 6 C 6 = 1. There's only 1 way you can do all the chores because they're the same.

Hope that made sense! Just remember, if order matters use a permutation, if order does not matter, then use a combination.
