In set notation this is B = {1, 4, 9}. 30 people answered a survey about whether they have a dog or a cat. The Venn diagram shows the information from the survey. 13 people have got a dog.

A Venn diagram in math can show how various sets of numerical data overlap with one another. To take a simple example, if one circle represents every number between 1 and 25 and another represents ...

One could reasonably argue that beyond four sets of elements, Venn diagrams lose their utility. The four-ellipse image is already pretty chaotic. Maybe for five-plus sets we should abandon visual ...

I haven’t done a roundup of Venn diagrams in several years. That’s a graph that shows sets and all possible overlaps of those sets. It works two-dimensionally when there are three or fewer sets.

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 diagrams are a simple and elegant way to represent the ...

A new rose has blossomed in the garden of mathematics: a flowery Venn diagram for 11 sets of objects. Venn diagrams use overlapping circles to show all possible relationships between sets.
