(Can be used with all boards, but questions taken from Edexcel or IB papers) 1. Following the same logic, we can write the formula for 3 circles Venn diagram: n (A ∪ B ∪ C) = n (A) + n (B) + n (C) – n (A ∩ B) – n (B ∩ C) – n (C ∩ A) + n (A ∩ B ∩ C) As we already know how the Venn diagram works, we are going to give some practical examples (problems with solutions) from the real life. We have not included three circle diagrams, as they will be covered in a separate lesson. Circles Total = E everything – (Not in A and Not in B), In A Only = Both Circles Total – Total in B, In A Only = The A Circle Total – Total in the intersection (A and B), In B Only = Both Circles Total – Total in A, In B Only = The B Circle Total – Total in the intersection (A and B), In the Intersection (A and B) = Total in B – In B Only, In the Intersection (A and B) = Total in A – In A Only.
