Given:


\begin{gathered} A=\lbrace1,2,4,7\rbrace \\ B=\lbrace1,5,6,7\rbrace \\ U=\lbrace1,2,4,5,6,7\rbrace \end{gathered}

To find:


(A\cap B)^(\prime)

Step-by-step explanation:

Using the property,


(A\cap B)^(\prime)=U-(A\cap B)

Here,


A\cap B=\lbrace1,7\rbrace

So, the property becomes,


\begin{gathered} (A\cap B)^(\prime)=\lbrace1,2,4,5,6,7\rbrace-\lbrace1,7\rbrace \\ (A\cap B)^(\prime)=\lbrace2,4,5,6\rbrace \end{gathered}

Final answer: Option B


(A\operatorname{\cap}B)^(\prime)=\lbrace2,4,5,6\rbrace
