$\huge \rm \fbox{Question :}$

If A and B are two sets such that A c B then , what is A U B ?

$\huge \rm \fbox{Answer :}$

A U B = B

$\huge \rm \fbox{Solution :}$

Let us assume that ,

• A = {1,2}
• B = {1,2,3} , A c B

Now ,

A U B = {1,2} U {1,2,3}

A U B = {1,2,3}

A U B = B [ because , B = {1,2,3} ]
