mly selected statistics student is found to be one who skipped their most recent class, what is the probability that he or she is retaking the course?

Suppose that, of all students enrolled in a statistics class, 8% skipped their most recent class (event S), 3% are retaking the course (event R), and 60% graduated from high school in the Oklahoma City area (event G). Also suppose that, of the students who are retaking the class, 20% skipped their most recent class. You may assume that event S and G are independent.a) If a statistics student is selected at random, what is the probability the student will have skipped his or her most recent class or will have graduated from high school in the Oklahoma City area (or both)?b) If a statistics student is selected at random, what is the probability the selected student will have skipped his or her most recent class and will be retaking the course?c) If a randomly selected statistics student is found to be one who skipped their most recent class, what is the probability that he or she is retaking the course?
