a bag contain 6 red,4 blue,2 green and 3 yellow marbles.

\r\n" );
document.write( " if four marbles are picked at random,what is the probability that  one is green,two are blue and one is red?\r\n" );
document.write( "\r\n" );
document.write( "We can pick the 1 green marble any of C(2,1) = 2 ways.\r\n" );
document.write( "We can pick the 2 blue ones any of C(4,2) = 6 ways.\r\n" );
document.write( "We can pick the 1 red one any of C(6,1) = 6 ways.\r\n" );
document.write( "\r\n" );
document.write( "The number of ways we can pick that is 2*6*6 = 72\r\n" );
document.write( "\r\n" );
document.write( "That's the numerator of the probability.\r\n" );
document.write( "\r\n" );
document.write( "The denominator of the probability is the number of ways we can pick \r\n" );
document.write( "any 4 marbles out of the 6+4+2=12.\r\n" );
document.write( "\r\n" );
document.write( "That's C(12,4) = 495 ways.\r\n" );
document.write( "\r\n" );
document.write( "So the probabiloity is 72 successful ways out of 495 possible ways.\r\n" );
