To find A' u B, you first need to find the complement of set A, which includes all elements that are not in set A. This can be denoted as A'. Then, you take the union (u) of set A' and set B, which includes all elements that are either in set A' or in set B or in both.In symbols, A' u B can be written as:A' = complement of set A

A' = {x : x is not in A}

A' u B = {x : x is in A' or x is in B}

A' u B = {x : x is not in A or x is in B}So, to find A' u B, you need to determine the elements that are not in A or are in B.
