What is the complement of a null set?

What is the complement of a null set?

What is the Complement of an Empty Set or Null Set? Empty set means there are no elements in the set, so the complement of an empty set or a null set is the universal set containing all the elements.

What is an example of a null set?

Any Set that does not contain any element is called the empty or null or void set. The symbol used to represent an empty set is – {} or φ. Examples: Let A = {x : 9 < x < 10, x is a natural number} will be a null set because there is NO natural number between numbers 9 and 10.

What is a complement in sets?

For any set A which is a subset of the universal set. U. , the complement of the set. A. consists of those elements which are the members or elements of the universal set.

Can empty set have complement?

The complement of the empty set is the universal set for the setting that we are working in. This is because the set of all elements that are not in the empty set is just the set of all elements. The empty set is a subset of any set.

Is zero an empty set?

What is the cardinality of a null set?

3. The cardinality of the empty set {} is 0. 0 . We write #{}=0 which is read as “the cardinality of the empty set is zero” or “the number of elements in the empty set is zero.”

What is the complement of 73?

The complement of 73 is the angle that when added to 73 forms a right angle (90° ).

Is null an element of null?

The null set can be an element of a set. (For example, it is an element of Y.) But the null set has no elements, and since X=∅, X has no elements and you cannot write v∈X for any v whatsoever, even ∅. ∅∈Y because it was written that it is, as clearly as can be.
