A school has 6 boys and 4 girls. If one boy captain and one girl vice-captain are to be chosen, how many ways are possible?

Answer and explanation

Correct answer: 24 ways

This problem uses the multiplication principle because two distinct roles must be filled. The captain must be a boy, so there are 6 choices for captain. The vice-captain must be a girl, so there are 4 choices for vice-captain. Every boy choice can be paired with every girl choice, giving 6 × 4 = 24 possible leadership pairs. Therefore, option D is correct. The result 10 comes from adding the group sizes and does not form pairs. The value 20 does not represent the required product, and 12 would also undercount the combinations. Since the roles and eligible groups are different, no further division is needed.
