Answer 2

Given,

$\[\begin{array}{l}A = \left\{ {2,3,5,7,11} \right\}\\B = \left\{ {2,4,6,8} \right\}\\C = \left\{ {1,3,5,7,9} \right\}\end{array}\]$

$\[A - \left( {B \cap C} \right) = ?\]$

Solution,

$\[\begin{array}{l}B \cap C = \left\{ {2,4,6,8} \right\} \cap \left\{ {1,3,5,7,9} \right\}\\ \Rightarrow B \cap C = \phi \end{array}\]$

Further solution,

$\[\begin{array}{l} = A - \left( {B \cap C} \right)\\ = \left\{ {2,3,5,7,11} \right\} - \phi \\ = \left\{ {2,3,5,7,11} \right\}\end{array}\]$

Hence, the value of$\[A - \left( {B \cap C} \right)\]$ is$\[\left\{ {2,3,5,7,11} \right\}\]$.
