Question

Is this a probability combination problem or permutation?

If I have 20 board members and need to choice 10 to be on a subcommittee, how many different subcommittees are possible?

Answer 1

These are combinations.

Answer 2

This is a combination problem.

\[\binom{20} {10} \]

Answer 3

\( \color{Black}{\Rightarrow 20c10 }\)

20 choose 10.

Answer 4

\( \color{Black}{\Rightarrow \binom{20}{10} }\)
