This math topic explores basic probability concepts, focusing on the union, intersection, and complement of events. Specifically, it comprises exercises regarding selecting appropriate formulas for cases like both events occurring, either event occurring, or an event not occurring. Problems involve understanding and applying formulas such as \( P(A \cup B) = P(A) + P(B) - P(A \cap B) \) for the union of two events, \( P(A \cap B) \) for the intersection, and \( P(A^c) = 1 - P(A) \) for the complement. It helps beginners grasp how to translate descriptions of probability events into mathematical expressions.
