Explanation:

Step1: Determine the percentage of students who earned a D

From the bar graph, the percentage of students who earned a D is \(10\%\).

Step2: Calculate the number of students

The formula to find the number of students is \(n=\text{Percentage}\times\text{Total number of students}\).

So \(n=0.1\times20\)
