Answer 2

Step-by-step explanation:

(I) A'={2,3,4,5,6,7,15,16,17,18,19}

B'={3,5,7,9,11,13,15,17,19}

(ii) A-B={8,9,10,11,12,13,14}-{2,4,6,8,10,12,14,16,18}

={9,11,13}

B-A={2,4,6,8,10,12,14,16,18}-{8,9,10,11,12,13,14}

={2,4,6,16,18}

A-B and B-A are not equal

(iii) (AUB)={8,9,10,11,12,13,14} U {2,4,6,8,10,12,14,16,18}

={2,4,6,8,9,10,11,12,13,14,16,18}

(A U B) '={3,5,7,1517,19}

A'={2,3,4,5,6,7,15,16,17,18,19}

B'={3,5,7,9,11,13,15,17,19}

A'B'={3,5,7,15,17,19}

(A U B.)'=A'B'
