\r\n" );
document.write( "First, notice that among 5 balls, there are exactly 1 ball of each of the 5 colors.\r\n" );

document.write( "(b)  Blue and green just are present in each selected sample, and they can be completed by either of the 3 remaining balls.\r\n" );
document.write( "\r\n" );
document.write( "     So the answer in this case is 3.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );

document.write( "(c)  The samples that contain neither blue nor green are comprised of other (remaining) colors.\r\n" );
document.write( "\r\n" );
document.write( "     There is only one possible triple of such kind.\r\n" );
document.write( "\r\n" );
