We want to choose 4 people and we have 6 people to choose from. This is a combination of 6, 4 by 4. Also called <em>six choose four</em>.

The following formula:

_rC_n=\frac{n!}{r!(n-r)!}

Is the combination of r objects choosen from a total of n. It's n choose r.

For our problem, we just need to compute the following:

_4C_6=\frac{6!}{4!(6-4)!}=\frac{6\times5\times4!}{4!2!} =\frac{6\times5}{2\times1} =15

Thus

\boxed{_4C_6=15}

Therefore the answer is 15 different combinations
