\n" ); document.write( "check the sum of elements in \"p%28X%29\" first\r
\n" ); document.write( "\n" ); document.write( "If the following is a probability distribution, the sum of elements in \"p%28X%29\"'s must be equal \"1\".\r
\n" ); document.write( "\n" ); document.write( "\"0.03%2B0.200%2B0.444%2B0.296=0.97\"\r
\n" ); document.write( "\n" ); document.write( "So, it is \"NOT\" a probability distribution. The sum of the \"p%28X%29\"'s is not \"1\", since \"0.97+%3C%3E1.000\".
\n" ); document.write( "
\n" );
