reading books last month
dot plot with categories 0,1,2,3,4,5,6 on the x - axis labeled books read and xs representing the number of students for each category

□ students

Explanation:

Step1: Count students who read 2 books

Looking at the graph, the column for 2 books has 10 'x's. So, number of students who read 2 books is 10.

Step2: Count students who read 3 books

The column for 3 books has 4 'x's. So, number of students who read 3 books is 4.

Step3: Count students who read 4 books

The column for 4 books has 9 'x's. So, number of students who read 4 books is 9.

Step4: Count students who read 5 books

The column for 5 books has 1 'x'. So, number of students who read 5 books is 1.

Step5: Count students who read 6 books

The column for 6 books has 7 'x's. So, number of students who read 6 books is 7.

Step6: Sum the counts

To find the total number of students who read at least 2 books, we sum the counts from steps 1 - 5: $10 + 4 + 9 + 1 + 7 = 31$.
