Answer:
Percentage = 66%
Explanation:
Let the number of students that pass be P.
Let the number of students that fail be F.
Given the following data;
Total number of students, T = 890 students
P = 300 students
To find the percentage that failed;
First of all, we would determine the number of students that failed using the mathematical expression given below;
Total students, T = P + F
890 = 300 + F
F = 890 - 300
F = 590


Percentage = 66.29 ≈ 66%
Therefore, the percentage of students that failed or didn't pass is 66%.
