When you're evaluating P(n, k), you are essentially saying there are n objects and you will need to arrange them in k spaces.
This is essentially the same as:
, which follows the formula:
If you're dividing by 4!, you are evaluating P(6, 2)
This is essentially the same as:
If you're dividing by 4!, you are evaluating P(6, 2)
