Let's talk about the difference between a combination or permutation.
00:04
Okay, what is a combination? well, with a combination, order does not matter.
00:10
So here, if i were to select events, a, b, and c, this would be different, or this would be the same as selecting events b, a, and c.
00:19
Whereas a permutation order does in fact matter.
00:24
So here, selecting events, a, b, and c is different than b, a, than c, even though the same events the order matters.
00:30
So let's suppose i want to visit five restaurants in a city with 10.
00:35
Does the order matter? nothing indicates that the order matters.
00:41
So it's not a permutation.
00:44
Order does not matter.
00:45
It's a combination...
