Consider the formula n (A B) = n(A) +n(B) - n(A B) (a) Show that

Question:

Consider the formula

n (A ∪ B) = n(A) +n(B) - n(A ∩ B)

(a) Show that this relation holds for A = {a, b, c, d} and B = {b, d, e, f, g, h}.

(b) Use a Venn diagram and explain why the relation holds for any two sets A and B.
