We are being asked more than one question on this problem, but at the beginning, for both of these questions, we're still going to need to determine whether we are dealing with a combination or a permutation.
00:14
Combination is what we use when order does not matter.
00:17
Permutation is what we use when order does matter.
00:20
In both of these scenarios, we are given no directions on which card we are getting first.
00:27
We know in both of these we are supposed to be being dealt five card hands, and we are given certain rules, certain restrictions for what can be in those hands.
00:38
But neither of these questions say anything about you need to draw a queen first, or you need to draw a jack first, you know, or something like that.
00:46
So because they aren't saying anything like that, we know both of these are going to be combinations.
00:52
We do not need to worry about using any permutations for this question.
00:57
Because we just don't need to care about the order.
01:00
We care about what the cards are, but we don't care which one comes first versus which one comes fifth as they're dealing.
01:07
Now, for our first question, it says from a 52 card deck, how many five card hands will have all face cards? now, it does tell us when we're talking about face cards that we are supposed to be talking about jacks, queens, and kings.
01:25
That's what we consider face cards.
01:26
So aces are not a thing, which aces shouldn't be considered face cards.
01:29
They don't have faces on them, but, you know, whatever...
