The notation $A \cap B$ represents the intersection of sets A and B, which means the set of elements that are common to both A and B. This notation represents the simultaneous occurrence of events A and B, which is the best choice for this scenario. The other notations represent different concepts: $A \cup B$ represents the union of sets A and B, which means the set of elements that belong to either A or B (or both); A│B and B│A represent conditional probabilities, which are not relevant to this scenario.

The Simultaneous Occurrence of Events a and B Is Represented A∪BA \cup BA∪B
