116,396,280 ways

Step-by-step explanation:

Two six-person committees are to be formed from 20 people.

The first 6 person committee can be formed in

²⁰C₆ ways = 38760 ways.

After forming this committee, there are 14 people left.

The second 6 person committee can be formed in

¹⁴C₆ ways = 3003 ways

The two committees can be formed in

38760 * 3003 ways = 116,396,280 ways
