330


840


5040


7920

Answer 3

\[ x= \frac{\text{factorial } 11 }{ \text{factorial } (11-4) } \]
\[ \ \ ~~~~~~~~~~~~~~~ \Updownarrow \]
\[ x=\frac{11 \times 10\times 9\times 8\times7\times6\times5\times4\times3\times2}{7\times6\times5\times4\times3\times2} \]
\[ \ \ ~~~~~~~~~~~ \Updownarrow \]
\[ x=\frac{39916800 }{5040} \]
\[ ~~~~~~~ \Updownarrow \]
\[ \LARGE x=7920 \]
which otpion would that be?
