| \begin{propriete}[ Triangle de Pascal ]
 | |
|     Soit $n$ et $k$ deux entiers naturels tels que $0 \leq k \leq n$.
 | |
|     \[
 | |
|         \coefBino{n}{0} = \coefBino{n}{n} = 1 \qquad \qquad \coefBino{n-1}{k-1} + \coefBino{n-1}{k} = \coefBino{n}{k}
 | |
|     \]
 | |
|     Il est possible de calculer ces coefficients binomiaux grâce au triangle de Pascale.
