Total outcome=50
50% marks = 50 out of 100
fail students=obtained marks less than 50=9+8=17
possible outcomes=17
probability of students who are fail in examination=possible outcome/total outcome
=17/50

Let total marks be 100
Passing marks is 50
If he gets 49 marks or less, he will fail.
And: 49/100
