    The number of ways to choose 3 girls from 14 girls is 14C3. Each of these ways can be combined with each of the 9C3 ways of choosing 3 boys from 9 boys. Therefore the total number of ways of choosing 6 students with equal numbers of boys and girls is given by: \[\large 14C3\times9C3=\frac{14\times13\times12}{6}\times\frac{9\times8\times7}{6}=you\ can\ calculate\]

    that's not one of the answer choices which is odd because it looks right
