To find the percentage of students who responded to the survey, we first need to determine the total number of students who answered and then calculate the percentage based on the total number of students surveyed.
From the chart, we can add up the number of students who play each instrument:
- Violin: 1
- Piano: 6
- Guitar: 2
- Drums: 3
Total students who play a musical instrument = 1 + 6 + 2 + 3 = 12 students.
Since the total number of students surveyed is 25, the percentage of students who responded to the survey is calculated as follows:
\[ \text{Percentage} = \left( \frac{\text{Number of students who responded}}{\text{Total number of students surveyed}} \right) \times 100 \]
\[ \text{Percentage} = \left( \frac{12}{25} \right) \times 100 = 48% \]
Therefore, the percentage of students who responded to the survey is 48%.
