To meet the criteria for the planning committee, we need to ensure that there are at least 2 students from each class (freshman and sophomore) and a total of 12 students on the committee.
Let's evaluate each of the provided options:
-
1 freshman and 11 sophomores: This option does not meet the requirement of having at least 2 students from the freshman class.
-
6 freshmen and 4 sophomores: This option satisfies the requirement of at least 2 freshmen and at least 2 sophomores. It totals 12 students.
-
0 freshmen and 12 sophomores: This option does not meet the requirement of having at least 2 students from the freshman class.
-
5 freshmen and 7 sophomores: This option also satisfies the requirement of at least 2 students from both classes, totaling 12 students.
From the given options, the viable solutions that meet the criteria are:
- 6 freshmen and 4 sophomores
- 5 freshmen and 7 sophomores
Therefore, the successful options are 6 freshmen and 4 sophomores, and 5 freshmen and 7 sophomores.
