Let \"y\"= probability they play in Superbowl
\n" ); document.write( "Let \"n\"= probability they do not
\n" ); document.write( "\"y+%2B+n+=+1\"
\n" ); document.write( "\"y+=+9n\"
\n" ); document.write( "\"9n+%2B+n+=+1\"
\n" ); document.write( "\"10n+=+1\"
\n" ); document.write( "\"n+=+1%2F10\"
\n" ); document.write( "\"y+%2B+%281%2F10%29+=+1\"
\n" ); document.write( "\"y+=+1+-+%281%2F10%29\"
\n" ); document.write( "\"y+=+9%2F10\"
\n" ); document.write( "The probability they play in next Superbowl is 9/10
