Question: De Morgans Laws for set theory state that if you have two sets A and B, then (a) (A U B) = A B i.e.

De Morgans Laws for set theory state that if you have two sets A and B, then

(a) (A U B) = A B i.e. the complement of the union is equivalent to the intersection of the complements

(b) (A B) = A U B i.e. the complement of the intersection is equivalent to the union of the complements

Use Venn diagrams to argue that De Morgans Laws are correct.
