Use the sets given in the example find the following A n B A

Use the sets given in the example find the following: A n B, A\' , and (A n B)\'

     U = {1,2,3,4,5,6,7,8}

     A={1,2,4,5,8}

     B={2,3,4,6}

Solution

A={1,2,4,5,8}

     B={2,3,4,6}

A n B={2,4}

A\'=U-A

A\'={3,6,7}

(A n B)\'= U- (A n B)

(A n B)\'={1,2,3,4,5,6,7,8}-{2,4}

(A n B)\'={1,3,5,6,7,8}
