Hello!

If all of committee members have equal rights, then to select 6 people from 7 candidates is the same as to select ONE people who is NOT in the committee. There are 7 ways to select one people, so there are** 7 ways** to select a committee. Also it is known as the number of combinations from 7 by 6, `C_7^6=C_7^1.`

If, for example, a committee has 1 chairman, then there are 7 ways for selecting a chairman and 6 ways to select a man not in a committee, 7*6=42 ways at all.

The answer for the simple question is **7 ways**.
