11. (5 Percentages on a professional entrance exam are described by the probability density [cy² (1-y), 0<y<l else Note 1: A value of y = 0.75 means their percentage is 75%. Note 2: You need to find the value of c. function fy(y) = { " where c is a positive constant. From a random selection of 6 exam scores, what is the probability at least 4 scores are above 80% ? Assume all exams scores are independent.
