1. The problem asks for the range of the number of books. 2. The range of a data set is the difference between the maximum and minimum values. 3. From the table, the number of books are: $0, 1, 2, 3, 4, 5$. 4. The minimum number of books is $0$ and the maximum number of books is $5$. 5. Calculate the range using the formula: $$\text{Range} = \text{Maximum} - \text{Minimum}$$ 6. Substitute the values: $$\text{Range} = 5 - 0$$ 7. Simplify: $$\text{Range} = 5$$ 8. Therefore, the range of the number of books is $5$.
