To solve the question, we need to determine whether set A is a subset of set B and also find the union of sets A and B. ### Step 1: Determine if A is a subset of B - Given sets: - \( A = \{a, b\} \) - \( B = \{a, b, c\} \) - A set \( A \) is a subset of set \( B \) (denoted as \( A \subseteq B \)) if every element of \( A \) is also an element of \( B \). - Check the elements of \( A \): ...
