Problem Solving (PS) | If a committee of 3 people is to be selected from among 5 married coup

Bunuel KarishmaB chetan2u

What if we start by first selecting 1 person from each of the married couples.

2C1 * 2C1 * 2C1 * 2C1 * 2C1 = 32

And then from these 5 people we can select any 3

5C3 = 10

I know this is definitely wrong as total number of ways can only be 10C3 = 120, but I what to know what am I missing ?
