Melany Duran · Answer 1

The proportion of all students who passed the course is 8/10.

Step-by-step explanation:

Total no. of students = 10

No. of students who passed the exam = 8

No. of students who failed the exam = 2

To find the proportion of students who passed the course, we will consider the no. of students who passed the examination papers in that course. So, the proportion of students who passed the course is 8/10.
