Question

Someone please help me. This is stat and reasoning subject.

Answer 1

Using the combination formula, it is found that there are 70 ways in which the four sales representatives can be chosen.

The order in which the representatives 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, 4 representatives are chosen from a set of 8, hence:

$C_{8,4} = \frac{8!}{4!4!} = 70$

There are 70 ways in which the four sales representatives can be chosen.
