Question

It says find each region of the given venn diagram with the proper amount.
N (A intersect B)=21
N (A intersect B intersect C) = 6
N (A intersect C) = 26
N ( B intersect C) = 7
N (B intersect C ' )= 25
N ( A intersect C ') =25
N ( C) = 40
N (A ' intersect B ' intersect C ')= 2

What are the steps to doing this problem? It's a triple venn diagram for A, B, and C

Answer 1

start with the middle

Answer 2

guess we should label A, B, C

Answer 3

since \(N(A\cap B)=21\) and you have already accounted for 6 of them, that leaves 20 for the rest of it
