MicoArrafi Ralat jawabanmu 7! / ( 3! . 4! )

MicoArrafi $$\begin{align} n&=~_{~5}^{10}C\\&=\frac{10!}{5!\times5!}\\&=\frac{\not10~^2\times9\times\not8~^2\times7\times\not6~^{\not2}}{\not5\times\not4\times\not3\times\not2}\\&=2^2\times9\times7\\&=252 \end$

$$\begin{align} \frac{n}{_{~3}^{36}C}&=\frac{252}{_{~3}^{36}C}\\&=~_3^7C\\&=\frac{7!}{3!\times4!}\\&=\frac{7\times\not6\times5}{\not3\times\not2}\\&=7\times5\\&=\boxed{35}\ \bold{(b.)} \end$
