To solve the problem, we need to analyze the relationship between the events A and B, given that A is a subset of B and that the probability of B is not zero. ### Step-by-step Solution: 1. **Understanding the relationship**: Since A is a subset of B (denoted as \( A \subseteq B \)), this means that all outcomes in A are also in B. Therefore, the intersection of A and B is simply A itself: \[ A \cap B = A \] ...
