1. What is the universality of empty set?The empty set (∅) is a subset of every set
2. What is the related fields?Crucial in logic, computer science (databases, algorithms), probability, and topology
3. Can a subset be the same as the whole set?Yes, a set can be a subset of itself. If the small pile has exactly the same toys as the big box, it is still a subset.
4. What is a proper subset?A proper subset is a smaller group that is not the same as the bigger group. It has fewer toys than the big box.
