PRACTICE PROBLEMS ON PROPERTIES OF SET THEORY

Commutative Property :

For any two sets A and B

(i) A U B = B U A

(ii) A n B = B n A

Associative Property :

For any three sets A, B and C

(i) A U (B U C) = (A U B) U C

(ii)A n (B n C) = (A n B) n C

Question 1 :

If P = {1,2,5,7,9}, Q = {2, 3,5,9,11}, R = {3, 4,5,7,9} and S = {2, 3, 4,5, 8}, then find (i) (P U Q) U R (ii) (P n Q) n S (iii) (Q n S) n R

Solution :

P = {1, 2, 5, 7, 9}

Q = {2, 3, 5, 9, 11}

R = {3, 4, 5, 7, 9}

S = {2, 3, 4, 5, 8}

(i) (P U Q) U R

(P U Q) = {1, 2, 3, 5, 7, 9, 11}

(P U Q) U R = {1, 2, 3, 4, 5, 7, 9, 11} -------(1)

(ii) (P n Q) n S

P n Q = {2, 5, 9}

(P n Q) n S = {2, 5} ------(2)

(iii) (Q n S) n R

Q n S = {2, 3, 5}

(Q n S) n R = {3, 5} ------(3)
