Question

say answer for P ={1,2,5,7,9,}​

Answer 1

Given:

• P = {1, 2, 5, 7, 9}
• Q = {2, 3, 5, 9, 11}
• R = {3, 4, 5, 7, 9}

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}.
