To solve the problem, we need to analyze the relation \( R \) defined by the set \( R = \{(a, b) : a \in A, b \in B, a \in b\} \) where \( A = \{1, 2, 3\} \) and \( B = \{3, 4\} \). ### Step-by-Step Solution: 1. **Identify the Sets**: - We have two sets: - \( A = \{1, 2, 3\} \) - \( B = \{3, 4\} \) ...
