4) The score of a student on a certain exam is represented by a number between 0 and 1. Suppose that the student passes the exam if this number is at least 0.55. Suppose we model this experiment by a continuous random variable S, the score, whose probability density function is given by: 4x for 0s xs; f(x)=. |4-4x for글xs1 otherwise 1) What is the probability that the student fails the exam? 2) What is the score that he will obtain with a 50% chance, in other words, what
