Le coefficient binomial (n k) est le nombre de possibilités de choisir k élément dans un ensemble de n éléments. The binomial coefficient can be interpreted as the number of ways to choose k elements from an n-element set. Er gibt an, auf wie viele verschiedene Arten man {\displaystyle k} bestimmte Objekte aus einer Menge von {\displaystyle n} verschiedenen Objekten auswählen kann (ohne Zurücklegen, ohne Beachtung der Reihenfolge). (n − k)! Thank you ! When we expand [latex]{\left(x+y\right)}^{n}[/latex] by multiplying, the result is called a binomial expansion, and it includes binomial coefficients. If we wanted to expand [latex]{\left(x+y\right)}^{52}[/latex], we might multiply [latex]\left(x+y\right)[/latex] by itself fifty-two times. This could take hours!
