Question: I want you to put into practice what you have learned about sets and counting. I want you to create three sets, set A, set B, and set C by going through the items in your wallet or purse.

Set A will be a list of all of these items.

Create Set B, from the items in Set A that you think are essential.

Create Set C, by taking the complement of Set B in Set A, i.e. all of the non-essential items in your wallet or purse.

Are sets B and C proper subsets of set A? Explain.
