Two-Set Problems
n(A ∪ B) = n(A) + n(B) - n(A ∩ B)n(A ∩ B) = n(A) + n(B) - n(A ∪ B)n(only A) = n(A) - n(A ∩ B)Three-Set Problems
n(A ∪ B ∪ C) = n(A) + n(B) + n(C) - n(A ∩ B) - n(B ∩ C) - n(A ∩ C) + n(A ∩ B ∩ C)n(exactly one) = n(A) + n(B) + n(C) - 2n(A ∩ B) - 2n(B ∩ C) - 2n(A ∩ C) + 3n(A ∩ B ∩ C)n(exactly two) = n(A ∩ B) + n(B ∩ C) + n(A ∩ C) - 3n(A ∩ B ∩ C)Problem-Solving Strategies
