Use a Venn diagram to illustrate the set of all months of the year whose names do not contain the letter R in the set of all months of the year. 5. Use a Venn diagram to illustrate the relationship A ⊆ B and B ⊆ C. 15. Use a Venn diagram to illustrate the relationships A ⊂ B and B ⊂ C. 6. Prove that A ∩ B = A ∪ B by giving an element table proof. 7. Prove that A ∩ B = A ∪ B by giving a proof using logical equivalence. 8. Prove that A ∩ B = A ∪ B by giving a Venn diagram proof. 9.
