    For the faculty we have 10 choose 4 and for the students we have 14 choose 5, so total combinations of

    \displaystyle {10 \choose 4}{14 \choose 5} = \dfrac{10 \cdot 9\cdot 8 \cdot 7}{4 \cdot 3 \cdot 2 \cdot 1} \cdot \dfrac{14 \cdot 13\cdot 12 \cdot 11 \cdot 10}{5 \cdot 4 \cdot 3 \cdot 2 \cdot 1}

     \quad= ( 10(3)(1)(7) )(14(13)(1)(11)(1)) = 210(2002) = 420420

    Answer:   420,420
