Question

what is universal set?​

Answer 1

Step-by-step explanation:

$\huge\blue{HELLO\:MATE}$

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. ... The region inside the circle represents the set A of odd whole numbers between 0 and 10.

Answer 2

In set theory, a universal set is a set which contains all objects, including itself. In set theory as usually formulated, the conception of a universal set leads to Russell's paradox and is consequently not allowed. However, some non-standard variants of set theory include a universal set.
