Hello,

aPb=b(b-1)(b-2)....(b-a+1) / a!

3P5=543/(321)=10

If we name the number of the employers 1,2,3,4,5

Here are the choices:

123,124,125,134,135,145,234,235,245,345 (total 10 choices)

Based on the problem above the answer is 10. Below is the solution: 

formula is 5! / 3! (5-3)! = 54321 / 32*2 = 10 combinations

There are 10 combination that are from 5 employees taken 3 at a time.
