2. Union of Sets is defined as the group of all elements that are members of one or both of the sets A and B, and is denoted by the symbol ___?
- A∪B
- A*B
- A-B
- A+B
Answer: A) A∪B
Explanation:
Union of Sets is defined as the group of all elements that are members of one or both of the sets A and B, and is denoted by the symbol A∪B.
3. All elements that belong to both A and B make up the intersection of two sets, denoted by ___?
- A∪B
- A∩B
- A*B
- A+B
Answer: B) A∩B
Explanation:

- A -- B
- A + B
- A - B
- A +- B
Answer: C) A - B
Explanation:

- Union
- Consequtive
- Complement
- Difference
Answer: C) Complement
Explanation:
A set's complement is the sum of all the elements of that set which do not belong to it, and it is referred to as Ac.
