Okay, here we have 25 players, two quarterbacks, 10 linemen, five running backs, five wide receivers and three tight ends.
00:13
I want to work out how many different teams with one quarterback, first of all.
00:19
So that will be i have two to choose from, so two choose one for the quarterbacks.
00:26
Then i want five line men.
00:30
I have 10 to choose from.
00:32
So it's 10 choose five.
00:35
10 c5.
00:37
I want two running backs.
00:38
I have five of those to choose from up here.
00:41
Five running backs.
00:43
Five choose two.
00:44
I want two wide receivers.
00:47
So again, five to choose from.
00:49
So five c2.
00:52
And one tight end.
00:53
And there are three of those choose from.
00:55
So three c1.
00:57
So, let your times together and that will give the answer.
01:03
Quick check, one quarterback, yep, that's right.
01:06
Five line men from 10, two running backs, two wide receivers and a five.
01:13
That's right.
01:14
So i can work out these on a calculator or manually.
01:20
It's not too hard this time...
