Question

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

Answer 1

Given:

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

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

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

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

To Find:

(P U Q) U R

Solution:

(P U Q) is the union of two given sets P and Q.

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

Now union of two sets (P U Q) and R will be,

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

Therefore, union of all three sets P, Q and R will be {1, 2, 3, 4, 5, 7, 9, 11}.

Answer 2

Answer:

solution = pUq ={1, 2,3,4,5,7,9,11}
