Answer 1

Hi ,

************************************************

We know that ,

If A, B , C are three sets ,

i ) A U B = { x/x€A or x € B }

ii ) An B = { x/x € A and x € B }

iii ) A - B={ x/x € A and x doesn't belongs to B}

iv ) A' = U - A

****************************************************
Now ,

i ) u - ( A - B )

ii ) ( A n B ) U ( A n C )

iii ) A - ( A U C )

or

( A - B ) n C

iv ) ( A n B ) - C

I hope this helps you.
