This math topic focuses on practicing probability operations involving the union, intersection, and complement of events. Specifically, the problems require identifying the correct probability operation based on a given description, such as "Both A and B happening," "Event A not happening," and "Either A or B happening." Each problem presents multiple choices like "A union B," "A intersect B," "Complement of A," and "A conditional on B," and the student has to select the correct name of the operation that matches the description. This is an introductory exercise in understanding basic set operations in probability.
