## How do you calculate repetition combinations?

The number of k-element combinations of n objects, with repetition is Cn,k = Cn+k-1,k = (n + k − 1 k ) = ((n k )) . It is also the number of all ways to put k identical balls into n distinct boxes, or the number of all functions from a set of k identical elements to a set of n distinct elements.
