times because of O repetition. Therefore there are 7!/(4!3!) different combinations = (n + r - 1)! / ((n - 1)! * r!), which is the formula that we are after. Combinations versus permutations, what's the difference? The difference is whether we care about the order. With ...
N Choose K Formula Then choose kformula is nearly identical to the combinations formula above, but the number of items in the sample is denotedk, and the total number of objects is denotedn. C(n,k) =n!/k!(n – k)! Combinations with Repetitions ...
Repetitions are just repeating numbers. They become important when it comes to choosing the right formula. 123 has no repetitions (each of those numbers is unique). 223 has the number 2 repeated. Allowingrepetitiondepends on your situation. For example: ...
Permutation Formula A permutation is the choice of r things from a set of n things without replacement and where the order matters. nPr= (n!) / (n-r)! Combination Formula A combination is the choice of r things from a set of n things without replacement and where order does not matter...

The permutation of a password always allows repetition: we will only deal with exponents! Now that we understand which formula we will use, let's define the elements that will appear there: nn— The number of possible characters; and kk— The length of the password. The number nn is nothi...
