Question

let
u = {22, 23, 24, 25, 26, 27, 28, 29, 30, 31}
a = {25, 26, 27, 28}
b = {22, 24, 26, 28, 30}
c = {23, 25, 26, 30, 31}
find the set.
u =

Explanation:

Step1: Define complement of universal set

The complement of a set \(U\) (denoted \(U'\)) is the set of all elements not in \(U\) within the universal context. Since \(U\) is defined as the universal set here, there are no elements outside of it.

Step2: Identify the complement set

There are no elements not contained in \(U\), so the complement is an empty set.
