To determine which options are viable for the prom committee consisting of 15 upperclassmen with at least one student from each grade, we must evaluate each option based on the specified requirements.
-
Option #1: 4 juniors and 12 seniors
- Total: 4 + 12 = 16 (Does not meet the requirement of 15 students)
-
Option #2: 15 juniors and 0 seniors
- Total: 15 (Meets the total requirement but does not include at least one senior; thus, it is not viable)
-
Option #3: 6 juniors and 9 seniors
- Total: 6 + 9 = 15 (Meets the total requirement and has both juniors and seniors; thus, it is viable)
Given this evaluation:
- Conclusion: Option #3: 6 juniors and 9 seniors is a viable solution.
