n(A)=15
\n" ); document.write( "n(B)=15
\n" ); document.write( "n(AUB) =n(A)+n(B)-n(A n B)
\n" ); document.write( "n(AUB) can be maximum when n(AnB) is zero
\n" ); document.write( "so max value of n(AUB) =15+15-0
\n" ); document.write( " =30
\n" ); document.write( "n(AUB) can be minimum when n(AnB) is maximum.that means n(AnB) =15
\n" ); document.write( "min n(AUB)=15+15-15
\n" ); document.write( " =15
\n" ); document.write( "n(AnB) is minimum when n(AUB) is maximum and n(AnB) is maximum when n(AUB) is minimum. .
\n" ); document.write( "hence max n(AnB)=15
\n" ); document.write( "min n(AnB)=0\r
\n" ); document.write( "\n" ); document.write( "
