Your image contains a handwritten mathematical problem set related to set theory and intersections of sets. Would you like me to clarify the questions, solve them, or provide explanations for any of them?

Here are five related questions to expand on this topic:

1. What are the basic properties of set operations like union and intersection?
2. How can Venn diagrams help in visualizing set operations?
3. What is the difference between a subset and an element of a set?
4. How do we determine the cardinality of a union or intersection of multiple sets?
5. Can we express set operations using logical operators?

Tip: When working with set operations, always check if the given sets are disjoint, overlapping, or subsets of one another. It simplifies calculations!
