+2446 \({x \choose y}=\frac{x!}{y!(x-y)!}\)
Knowing this formula will allow you to compute any input for the choose function. Now, let's compute the result.
| \({7 \choose 6}=\frac{7!}{6!*(7-6)!}\) | Let's simplify the denominator first. |
| \(\frac{7!}{6!*(7-6)!}=\frac{7!}{6!}\) | In order to simplify this, let's think about it this way... |
| \(\frac{7!}{6!}=\frac{7*6*5*...*1}{\hspace{3mm}6*5*...*1}\) | There is a lot that will cancel here. |
| \(7\) | |
