$\huge\underline\mathfrak\green{Required\:Answer:-}$

➢ 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’.

➢ Example: Let us say, there are three sets named as A, B and C. The elements of all sets A, B and C is defined as;

A={1,3,6,8}

B={2,3,4,5}

C={5,8,9}

Find the universal set for all the three sets A, B and C.

Answer: By the definition we know, the universal set includes all the elements of the given sets. Therefore, Universal set for sets A, B and C will be,

U={1,2,3,4,5,6,8,9}

Explanation: From the above example, we can see that the elements of sets A, B and C are altogether available in Universal set ‘U’. Also, if you observe, no elements in the universal set are repeated and all the elements are unique.
