Introduction to Sets (Numbers and Number Sense)

Taking every element of both the sets A and B, without repeating any element is called Union of

Sets.

• True

• False

Intersection of sets is the set of elements which are uncommon to both the given sets.

• True

• False

Universal Sets are Union of Sets.

• True

• False

The compliment of a set is a measure of a set's size, meaning the number of elements in the

set.

• True

• False

Any set is considered to be a subset of itself.

• True

• False

6. Which statements are considered as true about subsets?

• No set is a proper subset of itself.

• The empty set is a subset of every set.

• The empty set is a proper subset of every set except for the empty set.

• A subset is a set whose elements are all members of another set.

7. It enable students to organize information visually so they are able to see the relationships

between two or three sets of items.

• Logic Diagram

• Set Diagram

• Venn Diagram

• None of the choices

8. Which of the following are false about cardinality of sets?

• It is the number of elements in the empty set is zero.

• This works for sets with finitely many elements, but fails for sets with infinitely many elements.

• Choices A and B

• None of the choices

9. The given statements about null set/ empty set are true, except?

• Empty set/ null set is a set without any elements.

• The empty set is denoted by ∅ or {}.

• Null sets are used to simplify the calculations and are most often used while classifying all the

  odd items or those items that are considered to be rare.

• U = {N, M, I, X} from A = {N, X}, and B = {M, I}, is example of a null set.

10. It is defined as an organized collection of objects and can be represented in set-builder form or

roster form.
