A non-empty intersection means the events can occur simultaneously, but it does not guarantee independence. If one event is a subset of the other, the occurrence of the first strictly dictates the occurrence of the second, creating strong dependence despite the non-empty intersection.

Conditions: Events A and B have a non-empty intersection ($AB \neq \emptyset$).; Event A is a subset of event B ($A \subset B$).
