To meet the requirements for the committee selection, the solution must consist of a total of 12 students with at least 2 students from each class (freshmen and sophomores).
Let's analyze the options:
- 1 freshman and 11 sophomores: Not viable, as it does not meet the requirement of having at least 2 freshmen.
- 5 freshmen and 7 sophomores: Viable, as it meets the requirement of having at least 2 freshmen and at least 2 sophomores.
- 0 freshmen and 12 sophomores: Not viable, as it does not have any freshmen.
- 6 freshmen and 4 sophomores: Viable, as it meets the requirement of having at least 2 freshmen and at least 2 sophomores.
From this analysis, the viable solutions are:
- 5 freshmen and 7 sophomores
- 6 freshmen and 4 sophomores
So, the responses that are viable solutions are:
- 5 freshmen and 7 sophomores
- 6 freshmen and 4 sophomores
