Answer 1

To sind solution to a given set of values:

$\begin{gathered} \mu=\mleft\lbrace1,2,3,4,5,6,7\mright\rbrace \\ A=\mleft\lbrace2,4,5,6\mright\rbrace \\ B=\mleft\lbrace4,5,7\mright\rbrace \end{gathered}$

The determine the set with values having :

$A^1nB^1=\mleft\lbrace\text{ }\mright\rbrace$$\begin{gathered} A^1=\text{not in A} \\ A^1=\mleft\lbrace1,3,7\mright\rbrace \\ B^1=\mleft\lbrace1,2,3,6\mright\rbrace \end{gathered}$$A^1nB^1\text{ = }\mleft\lbrace1\text{ , 3}\mright\rbrace$

Hence the correct answer is Option A with the range of {1 , 3}
