All right.
00:03
So this is a multi -part question.
00:05
So in a typical bridge deck of cards, you have your four aces.
00:12
You have your four jacks.
00:17
You have your four tens.
00:20
And you have your four nines with the various suits.
00:25
So remember, suits are hearts, diamonds, the spades, and the clubs.
00:30
So our first task, is to answer the question about what if it could be any suit.
00:38
And so if you have any suit available, then that means you had four suits available here.
00:43
You had four suits available when you drew the second time.
00:48
You had four suits available when aaron drew the third time and four suits available when the fourth card got drawn.
00:56
So you do four times four times four in your calculator, and that'll get you 256 different ways.
01:04
Now for part b, the question is asking what if they have to be different suits.
01:16
So if they have to be different suits, when you draw that first one, you have four suits you can choose from, but then now it's saying that you can't have that same suit again, so there's three different ways that that could happen...
