## Which law deals with complement of a set?

Complement of Sets Properties i) Complement Laws: The union of a set A and its complement A’ gives the universal set U of which, A and A’ are a subset.

Also, the intersection of a set A and its complement A’ gives the empty set ∅..

## How do you find the complement?

To find the complement of an angle, subtract that angle’s measurement from 90 degrees. The result will be the complement.

## What are the 4 operations of sets?

Set Operations include Set Union, Set Intersection, Set Difference, Complement of Set, and Cartesian Product.

## What is the complement symbol?

## What do you call an empty set?

There is a special name for the set which contains no elements. This is called the empty or null set.

## Which of the following is a universal set?

A universal set is the set of all elements under consideration, denoted by capital U or sometimes capital E. Example: Given that U = {5, 6, 7, 8, 9, 10, 11, 12}, list the elements of the following sets. In Venn diagrams, the universal set is usually represented by a rectangle and labeled U.

## Which of the following sets is a universal set for the other four sets?

Hence (e) is the universal set for the other four sets.

## What is the complement of a set?

Complement of a Set: The complement of a set, denoted A’, is the set of all elements in the given universal set U that are not in A. In set- builder notation, A’ = {x ∈ U : x ∉ A}. The Venn diagram for the complement of set A is shown below where the shaded region represents A’.

## How do you describe a universal set?

A universal set is a set which contains all the elements or objects of other sets, including its own elements. It is usually denoted by the symbol ‘U’. Suppose Set A consists of all even numbers such that, A = {2, 4, 6, 8, 10, …} and set B consists of all odd numbers, such that, B = {1, 3, 5, 7, 9, …}.
