Venn diagram sorting the numbers 1 to 20: even numbers and multiples of 3

An example figure from the Venn Diagram Generator.

A Venn diagram sorting the numbers 1 to 20 into two overlapping circles, Even and Multiples of 3, with the numbers in neither outside the circles
The numbers 1 to 20 sorted into two overlapping circles named Even and Multiples of 3, inside a box marked U. 2, 4, 8, 10, 14, 16 and 20 are in Even only; 6, 12 and 18 are in both; 3, 9 and 15 are in Multiples of 3 only; and 1, 5, 7, 11, 13, 17 and 19 are outside both circles, in the lower right corner.

Answer key

  • n(U) = 20
  • n(Even) = 10
  • n(Multiples of 3) = 6
  • n(Even ∩ Multiples of 3) = 3
  • n(Even ∪ Multiples of 3) = 13
  • Even only: 2, 4, 8, 10, 14, 16, 20
  • Even and Multiples of 3: 6, 12, 18
  • Multiples of 3 only: 3, 9, 15
  • Neither: 1, 5, 7, 11, 13, 17, 19
