A Venn diagram shows the following elements distributed across three sets PPP, QQQ, and RRR, and the universal set E\mathcal{E}E:
- E={1,2,3,4,5,6,7,8,9,10,11,12,13,14,15}\mathcal{E} = \{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15\}E={1,2,3,4,5,6,7,8,9,10,11,12,13,14,15}
- Elements in P P\,P only: 1,21, 21,2
- Elements in Q Q\,Q only: 3,43, 43,4
- Elements in R R\,R only: 5,65, 65,6
- Elements in P∩Q P \cap Q\,P∩Q only: 7,87, 87,8
- Elements in Q∩R Q \cap R\,Q∩R only: 9,109, 109,10
- Elements in P∩R P \cap R\,P∩R only: 11
- Elements in P∩Q∩RP \cap Q \cap RP∩Q∩R: 12
- Elements outside the circles: 13,14,1513, 14, 1513,14,15
