Answer 1

Using the combination formula, it is found that 84 different groups of 6 people are possible from the 9 remaining friends.

The order in which the friends are chosen is not important, hence the combination formula is used to solve this question.

What is the combination formula?

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by:

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this problem, 6 friends are chosen from a set of 9, hence:

$C_{9,6} = \frac{9!}{6!3!} = 84$

84 different groups of 6 people are possible from the 9 remaining friends.
