\r\n" );
document.write( "There are  \"4%5E4\"  different codes of 4 digits long with the digits from 0 to 3 inclusive.\r\n" );
document.write( "\r\n" );
document.write( "They are equally likely and only one of these codes works.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So the probability under the question is  \"1%2F4%5E4\" = \"1%2F256\" = 0.003906  (rounded to six decimal places).    ANSWER\r\n" );
