document.write( "As the problem states, the criterion to pass an examination is to pass in each of the 5 subjects.\r\n" );

document.write( "\r\n" );
document.write( "The total number of possible outcomes for the entire examination is  \r\n" );
document.write( "\r\n" );
document.write( "     = 32  (since there are two possible outcomes - to pass or to fail,- for each subject).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, there are 32 possible outcomes, and there is only one outcome to pass, which is to pass in each of 5 subjects.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Thus, the number of outcomes to fail is  32-1 = 31.    ANSWER\r\n" );
