### Set Operations and Venn Diagrams

#### Question 1:
Given the following sets:

- **Set A**: \( \{1, 2, 5, 7\} \)
- **Set B**: \( \{2, 7, 8\} \)
- **Universal Set U**: \( \{1, 2, 3, 4, 5, 6, 7, 8\} \)

Evaluate the following operations:

1. **Union of A and B** (\( A \cup B \)):
   The union of sets A and B includes all elements that are in A, in B, or in both.
   
2. **Intersection of A and B** (\( A \cap B \)):
   The intersection of sets A and B includes only the elements that are in both A and B.
   
3. **Intersection of the complements of A and B** (\( \overline{A} \cap \overline{B} \)):
   The complement of a set A (\( \overline{A} \)) includes all elements in the universal set U that are not in A. The intersection of the complements of A and B includes all elements that are neither in A nor in B.
   
4. **Union of the complements of A and B** (\( \overline{A} \cup \overline{B} \)):
   The union of the complements of A and B includes all elements that are either not in A, not in B, or in neither. 

Use the universally accepted Venn diagram to help visualize these operations.
