S
To determine

To fill in the blanks of the statement “The crux of the combinatorial proof of the binomial theorem is that the number of ways to arrange kb's and (nk)a's in a row is .”

Explanation

Given:

The statement “The crux of the combinatorial proof of the binomial theorem is that the number of ways to arrange kb's and (nk)a's in a row is .”

In the combinatorial proof of binomial theorem, the expression (a+b)n can be expanded into products of n letters, where each letter is either aorb.

The number of arrangements of kb's and (nk)a<
