Question

A={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
(P'U'Q ‘U’ R

Answer 1

Answer:

in this case the "P" is "A"

(PU Q) = {1, 2, 5, 7, 9}U {2, 3, 5, 9, 11} ⇒ (PU Q) = {1, 2, 3, 5, 7, 9, 11} Now, (PU Q)U R = {1, 2, 3, 5, 7, 9, 11}

U {3, 4, 5, 7, 9}

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

Hence, (PU Q) U R =

=

{1, 2, 3, 4, 5, 7, 9, 11}.
