Question

if U={x:x less than or equal to 10;x€N} A={x:x€N & x is prime} & B={x:x€N &x is even} write AnB' in roster form
​

Answer 1

Given;

U = {x: x less than equal to 10, x € N}

A = { x:x €N, x is prime}

B = { x:x € N , x is even }

To find ;

A n B'

Solution;

set in set- builder form,

U={1,2,3,4,5,6,7,8,9,10}

A= { 2, 3, 5,7}

B = { 2,4,6,8,10}

AnB ={2}

So, (AnB)' = {1,3,4,5,6,7,8,9,10}

A n B' = {1,3,5,7,8,9}

In roster form;

(AnB)'= {x:x €N, x less than equal to 10 , x not equal to 2}

A n B' = { x:x € N, x is odd no.}
