Proof: Permutation Theorem - Permutation Formula Derivation

Proof of Permutation Theorem - Learn Permutation Formula Derivation. This video will guide will guide you step by step in getting the proof this formula. In this previous lecture we had learnt the introduction to permutations in math, now based on that concept we are learning Permutations theorem here and we learn Permutations Formula Derivation, which is -
P(n,r) = n!/(n-r)!, here n = total number items present & r = items taken at a time.
In permutation item represent any things that is to be arranged, may be letter, words, digits, number etc.
This Permutation is very useful in solving different types of question related to permutations mathematics.
I believe this Combination and Permutation tutorial was helpful for you.
