  3. A mathematical expression

  4. A geometric figure

Show answer
Correct Option: A
Explanation:

A set is a well-defined collection of distinct objects, which can be any type of entity, such as numbers, letters, shapes, or even other sets.

What is the symbol used to represent the union of two sets?

  1. ∩

  2. ∪

  3. −

  4. ×

Show answer
Correct Option: B
Explanation:

The union of two sets, denoted by ∪, is the set of all elements that are in either of the two sets.

What is the symbol used to represent the intersection of two sets?

  1. ∩

  2. ∪

  3. −

  4. ×

Show answer
Correct Option: A
Explanation:

The intersection of two sets, denoted by ∩, is the set of all elements that are in both of the two sets.

What is the symbol used to represent the complement of a set?

  1. ∩

  2. ∪

  3. −

  4. ×

Show answer
Correct Option: C
Explanation:

The complement of a set, denoted by −, is the set of all elements that are not in the given set.

What is the power set of a set?

  1. The set of all subsets of the given set

  2. The set of all elements of the given set

  3. The set of all complements of the given set

  4. The set of all unions of the given set

Show answer
Correct Option: A
Explanation:

The power set of a set is the set of all subsets of the given set, including the empty set and the set itself.

What is the Cartesian product of two sets?

  1. The set of all ordered pairs of elements from the two sets

  2. The set of all unordered pairs of elements from the two sets

  3. The set of all elements that are in both of the two sets

  4. The set of all elements that are not in either of the two sets

Show answer
Correct Option: A
Explanation:

The Cartesian product of two sets is the set of all ordered pairs of elements, where the first element is from the first set and the second element is from the second set.

Which of the following is a Venn diagram?

  1. A diagram that represents the relationship between sets

  2. A diagram that represents the distribution of data

  3. A diagram that represents the flow of information

  4. A diagram that represents the structure of a molecule

Show answer
Correct Option: A
Explanation:

A Venn diagram is a diagram that represents the relationship between sets, using overlapping circles to show the common elements between the sets.

Which of the following is a property of the union of two sets?

  1. The union of two sets is always a set

  2. The union of two sets is always larger than either of the two sets

  3. The union of two sets is always smaller than either of the two sets

  4. The union of two sets is always equal to the sum of the two sets

Show answer
Correct Option: A
Explanation:

The union of two sets is always a set, regardless of the nature of the elements in the sets.

Which of the following is a property of the intersection of two sets?

  1. The intersection of two sets is always a set

  2. The intersection of two sets is always larger than either of the two sets

  3. The intersection of two sets is always smaller than either of the two sets

  4. The intersection of two sets is always equal to the difference of the two sets

Show answer
Correct Option: A
Explanation:

The intersection of two sets is always a set, regardless of the nature of the elements in the sets.

Which of the following is a property of the complement of a set?

  1. The complement of a set is always a set

  2. The complement of a set is always larger than the given set

  3. The complement of a set is always smaller than the given set

  4. The complement of a set is always equal to the difference of the given set and the universal set

Show answer
Correct Option: A
Explanation:

The complement of a set is always a set, regardless of the nature of the elements in the set.

Which of the following is a property of the power set of a set?

  1. The power set of a set is always a set

  2. The power set of a set is always larger than the given set

  3. The power set of a set is always smaller than the given set

  4. The power set of a set is always equal to the Cartesian product of the given set with itself

Show answer
Correct Option: A
Explanation:

The power set of a set is always a set, regardless of the nature of the elements in the set.

Which of the following is a property of the Cartesian product of two sets?

  1. The Cartesian product of two sets is always a set

  2. The Cartesian product of two sets is always larger than either of the two sets

  3. The Cartesian product of two sets is always smaller than either of the two sets

  4. The Cartesian product of two sets is always equal to the union of the two sets

Show answer
Correct Option: A
Explanation:

The Cartesian product of two sets is always a set, regardless of the nature of the elements in the sets.

Which of the following is a distributive law of set operations?

  1. The union of two sets is distributive over the intersection of the two sets

  2. The intersection of two sets is distributive over the union of the two sets

  3. The union of two sets is distributive over the complement of one of the sets

  4. The intersection of two sets is distributive over the complement of one of the sets

Show answer
Correct Option: A
Explanation:

The union of two sets is distributive over the intersection of the two sets, meaning that the union of the intersection of two sets with a third set is equal to the intersection of the union of each of the two sets with the third set.

Which of the following is an associative law of set operations?

  1. The union of two sets is associative

  2. The intersection of two sets is associative

  3. The union of two sets is associative over the intersection of the two sets

  4. The intersection of two sets is associative over the union of the two sets

Show answer
Correct Option: A
Explanation:

The union of two sets is associative, meaning that the union of the union of two sets with a third set is equal to the union of the two sets with the union of the third set.

Which of the following is a commutative law of set operations?

  1. The union of two sets is commutative

  2. The intersection of two sets is commutative

  3. The union of two sets is commutative over the intersection of the two sets

  4. The intersection of two sets is commutative over the union of the two sets

Show answer
Correct Option: A
Explanation:

The union of two sets is commutative, meaning that the union of two sets is equal to the union of the two sets in the opposite order.
