Re: Venn diagram and Membership table

What exactly are you having trouble with?  Do you understand how to draw Venn diagrams and make membership tables?

Re: Venn diagram and Membership table

Make a Venn Diagram for (A - B) - C and then make another Venn Diagram for (A - C) - (B - C) and confirm they are the same.

Do the same for a membership table.

What is the problem?
