To determine the percentage of students who play video games for less than 10 hours per week, let's analyze the histogram in the image:

1. **Bins to Consider**: The relevant bins for "less than 10 hours per week" include the intervals:
   - 1.0–3.9 hours (22 students)
   - 4.0–6.9 hours (31 students)
   - 7.0–9.9 hours (41 students)

2. **Total Frequency for Less Than 10 Hours**:
   - Total = 22 + 31 + 41 = 94 students.

3. **Total Frequency (Overall)**: To find the total number of students, we sum all the frequencies in the histogram:
   - 22 + 31 + 41 + 27 + 21 + 20 + 10 + 6 + 3 + 19 = 200 students.

4. **Percentage**: The percentage of students who play video games for less than 10 hours per week is calculated by:
   \[
   \text{Percentage} = \left( \frac{94}{200} \right) \times 100 = 47\%
   \]

Thus, **47%** of students play video games for less than 10 hours per week.
