Answer

A'∩B' = {6,7,8}

Work Step by Step

Given, U={1,2,3,4,5,6,7,8} A={1,2,3,4} B={1,2,4,5} We need to find (A'∩B'). A' = all the elements of set'U' which are not there in set A = {5,6,7,8} B' = all the elements of set'U' which are not there in set B = {3,6,7,8} A'∩B'={5,6,7,8} ∩ {3,6,7,8} = {6,7,8} (All the common elements of set A' and the set B'). (AUB)' = all the elements of set'U' which are not there in set AUB = {6,7,8}
