The score of a student on a certain exam is going to be a number between 0 and 1. Think of it as the percentage of correct answers on the exam. Suppose the student passes the exam if their score S is at least 0.60 and fails otherwise. If the probability density function of a student score S is given by 4x f(x) = { 4- 4x otherwise What is the probability that the student fails the exam?

Question
The score of a student on a certain exam is going to be a number between0 and 1. Think of it as the
percentage of correct answers on the exam. Suppose the student passes the exam if their score Sis
at least 0.60 and fails otherwise.
If the probability density function of a student score S is given by
4x
f(a) =
4 4x <a <1.
otherwise
What is the probability that the student fails the exam?
O 0.18
O 0.50
O 0.68
O 0.595
