Determining Subsets of a Set

"For the first SLP 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. Submit a one to two page paper with this information by the end of this module. "
