Answer:
9 students
Explanation:
Assuming that these dots represent students, let us begin with the amount of students that answered 8 questions right;
Students who got 8 answers right ⇒ 4 students,
Students who got 8 answers right ⇒ 3 students,
Students who got 10 answers right ⇒ 2 students
Now we are to compute the value of the students who received 8 or more answers right, provided the questions are out of 10;
Students who received 8 or more answers right; 4 + 3 + 2 = 9 students
Solution; 9 students
