Hello everyone,

I am really new to discrete and totally dont get it!!

I have a question that I have no idea how to get started or really approach it.

It is a Set theory question. I really appreciate it if someone can give me the step by step procedure of how to solve it and explanations so I can use it as a learning guide.

THANK YOU!!!
