Does the value of K have to be integer in binomial theorem, I assume it does but want to double check (1 Viewer)

And what happens if we find K which is not an integer

Yes k needs to be integer.

nCk is just the number of permutations in binomial theorem.

Let say you want find the number permutation of XXXYY. That is just 5C3 if you choose 3 X's or equivalently 5C2 if you choose 2 Y's.

As an exercise take a look at multinomial distribution
