Q2 Evil TA 8 Points An evil TA is proposing a new grading scheme for CSE 312: The final grade will only come from PSets, and that a student passes the course if and only if they get full points for at least 4 out of 5 PSets. Assume the student's scores across the psets are independent of each other. For the following questions, assume that the probability that each student can score full marks on a PSet is 0.60. Q2.1 1 Point Let X be the number of PSets a student gets full marks on. So: X ~ Bin(n,p) Hint: What does a binomial r.v. represent? What is n?
