Answer 2

Answer:

n(A U B) = n(A) + n(B) - n(A ∩ B )

Step-by-step explanation:

The relation between n (A), n (B), n (A ∩ B) and n (A U B) can be given as follows : n (A U B) = n (A) + n (B) - n (A ∩ B) - Here, the union of A & B is equal to the sum of elements of A and elements of B and then subtracting the intersection of A & B from it.
