TLDR
Permutations are the number of configurations you can get out of a given set of values that require the factoring in of order. The formula for the calculation of permutation goes like this: n!/(n-r)! There are 720 possible permutations, out of which, the correct one unlocks our combination lock, the probability of which would be 0.13 percent in case we forgot what the combination was. Permutation is also used for hashing in cryptography and in inter-leaver modules of error correcting algorithms like turbo code.via the TL;DR App
