Step 1

1 of 3In order to solve this equation, we need to use the formula for the number of combinations, $_nC_r$ of $n$ things taken $r$ at a time.

$_nC_r=\dfrac{n!}{(n-r)!r!}$

Based on the problem, we have $n=6$ which represents the number of employees, and $r=2$ which represents the number of employees chosen.
