DRAW A VENN DIAGRAM AND USE THE GIVEN INFORMATION TO FILL IN THE NUMBER OF ELEMENTS IN EACH REGION. (show all your work) n(A ∩ B) = 21, n(A ∩ B ∩ C) = 6, n(A ∩ C) = 26, n(B ∩ C) = 7, n(A ∩ C’) = 20, n(B ∩ C’) = 25, n(A’ ∩ B’ ∩ C’) = 2, n(C) = 40
Draw 3 overlapping circles. They are A, B and C
Draw a rectangle around all of them. That is for the elements that are not in A,B or C
Start with this n(A ∩ B ∩ C) = 6
Now work outwards
