Question

P = {-1, -3, -5, 0,4, 9 } Q = {0, 3, 5, 11} Find P U Q ​

Answer 1

(P ∪ Q) ∪ R (P ∪ Q) = {1, 2, 5, 7, 9} ∪ {2, 3, 5, 9, 11} = {1, 2, 3, 5, 7, 9, 11} (P ∪ Q) ∪ R = {1, 2, 3, 5, 7, 9, 11} ∪ {3, 4, 5, 7, 9} = {1, 2, 3, 4, 5, 7, 9, 11} (ii) (P ∩ Q) ∩ S (P ∩ Q) = {1, 2, 5, 7, 9} ∩ {2, 3, 5, 9, 11} = {2, 5, 9} (P ∩ Q) ∩ S = {2, 5, 9} ∩ {2, 3, 4, 5, 8} = {2, 5}Read more on Sarthaks.com - https://www.sarthaks.com/959926/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
