• Select one of the Venn diagrams.

• Drag and drop the shapes into the correct position on the Venn diagram.

  
  

   

Look at the group of animals shown below. You will notice both similarities and differences among them. When you work with groups, often similarities between the members result in two sets completely overlapping. When this occurs, the second set is called a subset of the first. For example, if every element of set B is also a member of set A , then you say B is a subset of A , and you write B A .

When referring to the animals, if A = {animals with fur} and B = {black and white animals}, then B A because all the black and white animals also have fur.

 

If U is the set of all animals in the picture above, then the Venn diagram showing B A would look like this.
