In how many ways a committee, consisting of 5 men and 6 women can be formed from 8 men and 10 women?

  • A.266
  • B.5040
  • C.11760
  • D.86400

Answer: C

The men and the women are chosen from separate pools, so the counts multiply.

\[ {}^{8}C_{5} \times {}^{10}C_{6} \]

\[ = 56 \times 210 = 11{,}760 \]

Using \( {}^{8}C_{3} \) and \( {}^{10}C_{4} \) gives the same values, since choosing whom to include is equivalent to choosing whom to leave out.
