Binomial coefficient
Let $0 \leq k \leq n$ for $k,n \in \mathbb{n}$ then define the binomial coefficient of $n$ choose $k$ as
$$\binom{n}{k} = \frac{n!}{k!(n-k)!}.$$Let $0 \leq k \leq n$ for $k,n \in \mathbb{n}$ then define the binomial coefficient of $n$ choose $k$ as
$$\binom{n}{k} = \frac{n!}{k!(n-k)!}.$$
