[AI-generated answer — Bot GPT 3.5]

To find the percentage of classes with under 18 students, we need to add up the frequencies for classes with 17 students or less.

This includes:
- 4 classes with 14 students
- 5 classes with 15 students
- 3 classes with 16 students
- 3 classes with 17 students

Adding these numbers together: 4 + 5 + 3 + 3 = 15 classes

Out of the total number of classes (4+5+3+3+4+2+1 = 22 classes), 15 classes have under 18 students.

To find the percentage, we divide the number of classes with under 18 students (15) by the total number of classes (22), and multiply by 100:

(15 / 22) x 100 = 68.18%

Therefore, 68.18% of the classes have under 18 students.
