Scenarios and asked to determine whether we should use a combination or a permutation for each one of them.
00:06
And so a permutation is where the order matters.
00:09
So picking the red ball first and then the blue ball is different than blue and then red.
00:17
A combination is where the order doesn't matter, where you only just care what you end up with.
00:22
So for the first one, when you grab a handful of candy out of a bag, we don't really care which piece we grabbed first and second and third because you end up with the same candy.
00:34
The order really doesn't matter.
00:36
So this would be a combination.
00:40
For number two, if there's four, i think it says teachers are selected to research some course options.
00:47
Because there's no roles here, it's not like someone's the leader and then the next person is something else.
00:53
It doesn't really matter what order you pick those four people in.
00:55
It's gonna be the same four people on the committee.
00:58
So that is also a combination because order doesn't matter...
