Sets \( A \) and \( B \) are defined as follows. \( \begin{array}{l}A=\{d, e, j\} \\ B=\{a, e, h\}\end{array} \) Answer each part below. Write your answer in roster form or as \( \varnothing \). (a) Find the intersection of \( A \) and \( B \). \( A \cap B=\square \) (b) Find the union of \( A \) and \( B \). \( A \cup B=\square \)

Let's analyze the sets \( A \) and \( B \): \[ A = \{d, e, j\} \\ B = \{a, e, h\} \] ### (a) Intersection of \( A \) and \( B \) (\( A \cap B \)) The **intersection** of two sets consists of elements that are **common to both sets**. - **Common Element:** \( e \) \[ A \cap B = \{e\} \] ### (b) Union of \( A \) and \( B \) (\( A \cup B \)) The **union** of two sets includes **all distinct elements** from both sets. \[ A \cup B = \{a, d, e, h, j\} \] --- **Final Answers:** (a) \( A \cap B = \{e\} \) (b) \( A \cup B = \{a, d, e, h, j\} \)
