1. Which of the following is/are the basic set operation?

1. Union of Sets
2. Intersection of Sets
3. Difference of Sets
4. All of the above

Answer: D) All of the above

Explanation:

The following are the basic set operation -

1. Union of Sets
2. Intersection of Sets
3. Difference of Sets

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 ___?

1. A∪B
2. A*B
3. A-B
4. 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 ___?

1. A∪B
2. A∩B
3. A*B
4. A+B

Explanation:

All elements that belong to both A and B make up the intersection of two sets, denoted by A ∩ B.

4. Those elements that belong to A but not to B make up ___, the difference between two sets A and B?

1. A -- B
2. A + B
3. A - B
4. A +- B

Explanation:

Those elements that belong to A but not to B make up A - B, the difference between two sets A and B.

5. A set's _____ is the sum of all the elements of that set which do not belong to it, and it is referred to as Ac?

1. Union
2. Consequtive
3. Complement
4. Difference

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.

6. When two sets A and B are symmetrically different, then ____ represents the set containing all elements that are in either of them but not in both?

1. A +- B
2. A ⨁ B
3. A* B
4. A U B

Explanation:

When two sets A and B are symmetrically different, then A ⨁ B represents the set containing all elements that are in either of them but not in both.
