Answer:
Explanation:
To find the percentage of students who passed the exam, we can divide the number of students who passed by the total number of students and then multiply by 100 to get a percentage:
Percentage of students who passed = (660/950) x 100
≈ 69.47%
≈ 69% (rounded to the nearest percent)
Therefore, approximately 69% of the students passed the exam.
To find the percentage of students who did not pass the exam, we can subtract the percentage of students who passed from 100:
Percentage of students who did not pass = 100% - 69%
= 31%
Therefore, approximately 31% of the students did not pass the exam.
