1. ## married couples

There are 5 couples. We will choose 4 persons but we want just 2 of them to be married. How many ways are there?

My way:C(5,1):We choose 1 couple.
C(8,2): We choose 2 persons.
But we don't want married couples. There were 4 married couples.We choose 1 among them and this makes 4.
24.5=120?

2. ## Re: married couples

Looks correct to me.

Many Thanks.
