Question 294696
Are they the same people who failed in each course?
Do all the students take all of those courses?
Are there other courses?
And how do you know?
Let's say there are 100 students
10 failed science
20 failed commerce
30 failed arts
That is 60 failures out of 100. 60/100 3/5
or is it 60 out of 300. 60/300= 20/100=1/5
