Maths : Set Language : Book Back, Exercise, Example Numerical Question with Answers, Solution : Exercise 1.4: Properties of Set Operations

Exercise 1.4

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 Q) R

(ii) (P Q) S

(iii) (Q S) R



2. Test for the commutative property of union and intersection of the sets

P = { x : x is a real number between 2 and 7} and

Q = { x : x is a rational number between 2 and 7}.



3. If A = {p,q,r,s}, B = {m,n,q,s,t} and C = {m,n,p,q,s}, then verify the associative property of union of sets.



4. Verify the associative property of intersection of sets for A = {−11, √2, √5, 7}, B = { √3, √5, 6, 13} and C = { √2, √3, √5 , 9}.



5. If A={ x : x = 2n , n W and n<4}, B = {x : x = 2n, n and n 4} and C = {0, 1, 2, 5, 6} , then verify the associative property of intersection of sets.
