Title: Consider the following formulas: nPr = (n!/(n-r)!) and nCr = (n!/(n-r)!r!). Giv Post by: ryobu on Sep 27, 2015 Consider the following formulas: nPr = (n!/(n-r)!) and nCr = (n!/(n-r)!r!).
Given the same values for n and r in each formula, which is the smaller value, P or C? How does this relate to the concept of counting the number of outcomes based on whether or not order is a criterion?

For example, ABC is equivalent to ACB and would not be counted twice. If, however, r is 0 or 1 then nPr = nCr.
