This is usually written n P k. C n r r. There are many formulas involved in permutation and combination concepts.

So we adjust our permutations formula to reduce it by how many ways the objects could be in order because we arent.

N r 1 Multiplying and divided by n r n r 1. 21 by the method of Mathematical Induction we should check it for n 1 and then to prove the implication that if the formula is true for the positive integer k then it is true for the next integer k1. P n r n n - r. A permutation is the choice of r things from a set of n things without replacement and where the order matters.
