Explanation:

Step1: Analyze the number of students for each non - zero count

For 1 time: There are 6 'X's.
For 2 times: There are 3 'X's.
For 3 times: There are 4 'X's.
For 4 times: There are 9 'X's.

Step2: Sum up the number of students

We need to find the sum of the number of students who went down 1, 2, 3, and 4 times. Using the formula \(6 + 3+4 + 9\).
First, \(6+3=9\), then \(9 + 4=13\), and finally \(13+9 = 22\).

22
