We were able to determine the number of elements in the union of two sets with the formula

n(A ∪ B) = n(A) + n(B) - n(A ∩ B).

Can you determine a formula for finding the number of elements in the union of three sets? In other words, write a formula to determine n(A ∪ B).

The formula will contain each of the following: n(A), n(B), n(C), n(A ∩ B ∩ C'), n(A' ∩ B ∩ C), and 2n(A ∩ B ∩ C)
