Question

Let U = {a, b, c, d, e, f, g}, A = {a, c ,f , g}, B = {f, g, b, d}

Verify:

(a) (A ∪ B)' = (A' ∩ B')

(b) (A ∩ B)' = (A' ∪ B')

Answer 1

Answer:

A = {2, 4, 6}

B = {1, 2, 3}

(b) P = {a, e, i, o, u}

Q = {a, b, c, d}

(c) X = {x : n ∈ N, x = 2n, n < 4}

Y = {x : x is an even number less than 10
