ans is taking a course in probability theory. Discussion sessions with the class TA (teaching assistant) conflict with Hans's trips to the beach. Hans has to decide between attending TA sessions, which might help him do better in the probability course, and going to the beach. Hans learns that90 % of past students who did not attend TA sessions received a grade of B or below in the course. Hans also learns that14 % of past students received a grade higher than B. After some thought, Hans decides to attend the TA sessions. Not all of his classmates share his decision; in fact, only4 out of every9 of his classmates attend discussion sessions with the TA. Compute the probability that Hans will receive a grade higher than a B in the course. Round your answer to two decimal places. (If necessary, consult alist of formulas.)
