1. The problem involves finding unions, intersections, and complements of sets A, B, and C, and then indicating certain set relationships on a Venn diagram. 2. Given sets: - $U = \{a, b, c, d, e, f, g\}$ - $A = \{a, b, c, d, e\}$ - $B = \{a, c, e, g\}$ - $C = \{b, e, f, g\}$ 3. Calculate each requested set operation: (i) $A \cup B = \{a, b, c, d, e\} \cup \{a, c, e, g\} = \{a, b, c, d, e, g\}$ (ii) $A \cap B = \{a, b, c, d, e\} \cap \{a, c, e, g\} = \{a, c, e\}$ (iii) $A \cup C = \{a, b, c, d, e\} \cup \{b, e, f, g\} = \{a, b, c, d, e, f, g\}$ (iv) $B \cap A = A \cap B = \{a, c, e\}$ (v) $A \cap (B \cap C) = A \cap (\{a, c, e, g\} \cap \{b, e, f, g\}) = A \cap \{e, g\} = \{e\}$ (vi) $(A \cap A')' = (\emptyset)' = U = \{a, b, c, d, e, f, g\}$ since $A'$ is the complement of $A$ in $U$ and $A \cap A' = \emptyset$. 4. For the Venn diagram relationships: (i) $A'$ is the complement of $A$ in $U$, so $A' = \{f, g\}$. (ii) $A' \cap B' = \{f, g\} \cap (U \setminus B) = \{f, g\} \cap \{b, d, f\} = \{f\}$. (iii) $A' \cap B = \{f, g\} \cap \{a, c, e, g\} = \{g\}$. (iv) $(A \cap B)' = (\{a, c, e\})' = U \setminus \{a, c, e\} = \{b, d, f, g\}$. (v) $(A \cup B)' = (\{a, b, c, d, e, g\})' = U \setminus \{a, b, c, d, e, g\} = \{f\}$. 5. These set relationships can be represented on a Venn diagram with three overlapping circles labeled A, B, and C inside the universal set $U$. The complements and intersections correspond to shaded regions outside or inside these circles as per the above results. Final answers: (i) $\{a, b, c, d, e, g\}$ (ii) $\{a, c, e\}$ (iii) $\{a, b, c, d, e, f, g\}$ (iv) $\{a, c, e\}$ (v) $\{e\}$ (vi) $\{a, b, c, d, e, f, g\}$ Venn diagram sets: (i) $A' = \{f, g\}$ (ii) $A' \cap B' = \{f\}$ (iii) $A' \cap B = \{g\}$ (iv) $(A \cap B)' = \{b, d, f, g\}$ (v) $(A \cup B)' = \{f\}$
