So if you have a committee of three people to be selected, and we are considering like five couples.
00:07
So this means that here what we have is 10 people, right? so what we want to compute is the probability that we will not include like a married couple here in this three.
00:25
So basic, what we need to do is for the first one that we select, we have 10 people and one select three.
00:34
So for the first one, the first one, we have like, in this case, we need to select like, we have 10 possibilities here, right? and in this case, i have like 10 possibilities and i want to select just one.
00:55
So basically what i have is this here.
00:59
And then basically what i have is now that i've select like one of the people here that i have, so this next person cannot be like either the first person that i selected or cannot be like, in this case, the other pair of like the merry couple.
01:21
So basically now i still have like nine people to select from because i before i had 10, but now i have nine...
