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