From 20 students and 6 faculty.
00:03
We want to know the probability that they will consist of 2 students and 2 faculty members.
00:10
So we have 2 students and 2 faculty members.
00:15
So let's see how many committees we can choose.
00:17
There's 26 people, so we don't care about the order, so we're going to get a combination of 26 people.
00:24
We're going to choose 4.
00:25
So let's go get that real quick.
00:28
We're going to go choosing 4.
00:29
That's going to be 14 ,950 different ways we can choose the committee.
00:37
Now we want 2 students and 2 faculty members.
00:41
So how can we choose the 2 students? we'll take a combination of 20, picking 2 at a time.
00:47
