FAQs on Union and Intersection of Sets, Difference of 2 Sets and Complement of Set

Question 1

1. What is the union of two sets?

Accepted Answer

The union of two sets is a new set that contains all the distinct elements from both sets. In other words, it combines all the elements of both sets without any repetitions.

Question 2

2. How is the intersection of two sets defined?

Accepted Answer

The intersection of two sets is a new set that contains only the elements that are common to both sets. It includes all the elements that are present in both sets.

Question 3

3. What is the difference between two sets?

Accepted Answer

The difference of two sets is a new set that contains the elements that are present in the first set but not in the second set. It excludes any elements that are common to both sets.

Question 4

4. How can the complement of a set be determined?

Accepted Answer

The complement of a set is the set of all elements that are not present in the given set but belong to a universal set. To determine the complement of a set, you need to know the universal set and subtract the elements of the given set from it.

Question 5

5. Can the union and intersection of sets be empty?

Accepted Answer

Yes, the union and intersection of sets can be empty. If two sets do not have any common elements, their intersection will be an empty set. Similarly, if two sets do not have any common elements, their union will also be an empty set.
