Answer 2

Answer:

the given formula is wrong

because actual one is ..

n( AUB ) = n(A) + n(B) - n(A intesection B )

Step-by-step explanation:

it means

(number of elements in A union B) = (number of elements in A) + (number of elements in B) - (number of elements in A intersection B )

In set theory UNION means all th elements in both A and B by taking common elements only once

In set theory INTERSECTION means taking the elements which are common in both A and B

im sorry i dont know how to verify by venn diagram

But

I hope it helps u
