A binomial probability experiment is conducted with the given

\n" ); document.write( "independent trials of the experiment.\r

document.write( "x's marked on them and the others are blank. You reach in \r\n" );
document.write( "the hat and draw one slip at random.  You note whether or\r\n" );
document.write( "not it has an x on it. Put the slip of paper back.  Shuffle \r\n" );

document.write( "one with an x on it or not, put it back and shuffle.  Continue \r\n" );
document.write( "until you have drawn a slip 9 times. What is the probability \r\n" );
document.write( "that you drew a slip with an x on it 3 or fewer times?\r\n" );
