This note takes you through the application problems that are based on Sets and Venn Diagrams. Some of the problems, though simple may be time consuming.

Mathematicians grow an 11-set Venn diagram rose It may look like a flower, but this is actually a new Venn diagram -- one that for the first time manages to represent 11 sets of data.

Venn had initially used diagrams developed by the Swiss mathematician Leonard Euler to show some relationships between sets, which he then developed into his famous Venn diagrams.
