What is universal set in Venn diagram?​

Answer 1

Answer:

the set which contains all the other set EG set A,B  is called universal set

Explanation:

A universal set (usually denoted by U) is a set which has elements of all the related sets, without any repetition of elements. Say if A and B are two sets, such as A = {1,2,3} and B = {1,a,b,c}, then the universal set associated with these two sets is given by U = {1,2,3,a,b,c}.

The English mathematician John Venn (1834−1923) began using diagrams to represent sets.This larger set is called the universal set, and is usually given the symbol E. In a Venn diagram, the universal set is generally drawn as a large rectangle, and then other sets are represented by circles within this rectangle.
