document.write( "The number of all possible pairs is  \"C%5B31%5D%5E2\" = \"%2831%2A30%29%2F2\" = 31*15 = 465.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Of them, ONLY one pair satisfies the problem's requirement.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, the probability to get this happy final choice is  P = \"1%2F465\".    ANSWER\r\n" );
