Hey mate here's your answer ⤵️

Union of Sets

The Union of two sets A and B is the set of all the elements present in A or B or both. We will take the common elements at once only. It is denoted with the symbol “∪” read as “union”.

Symbolically,

A∪B = {x: x ∈A or x ∈B}

Union of two Joint Sets

If A and B are two finite sets and there is some common elements within them, that is, A∩B≠∅

Then,

n (A∪B) =n (A) +n (B)-n (A∩B)

Hope it was helpfulll ✌️
