Answer:
I two groups are formed: 18 students
If 3 groups are formed: 12 students
Explanation:
We will answer this problem based on two occurrences:
1. The students chose to form only two groups:
If the students chose to form only two groups, the number of students in each group will be got by dividing the total number of students by 2. this will be 36/2 = 18. Therefore, there will be 18 students per group if only 2 groups were formed.
2. The students chose to form three groups:
If the students chose to form three groups, we will divide the total number of students by 3. this will be 36/3 = 12. Therefore, there will be 12 students per group if only 3 groups were formed.
