Explain the difference between combination and permutation in your own words. Give examples.

torisob [31]

Apparently, we use "Permutation" when order doesn't matter. In that way, only possible outcomes can be calculated.

P (n, r) = n! ( (n - r)!

Unlike, We use "Combination" when order does matter. Combination gives us all possible values.

C (n, r) = n! / (n - r)! r!

Hope this helps!
