A bag contains 4 red, 6 blue, 4 yellow, and 2 green marbles.

\n" ); document.write( "probability that in 3 successive draws you get exactly one blue,
\n" ); document.write( "one red and no green?
\n" ); document.write( "

\r\n" );
document.write( "That means you MUST get exactly 1 red, exactly 1 blue, and \r\n" );
document.write( "exactly 1 yellow. Let R&B&Y mean that you draw a red first,\r\n" );
document.write( "a blue second, and a yellow third.  Since it does not matter\r\n" );
document.write( "what order they are drawn in, the desired probability is:\r\n" );
document.write( "\r\n" );
document.write( "P(R&B&Y)+P(R&Y&B)+P(B&R&Y)+P(B&Y&R)+P(Y&R&B)+P(Y&B&R) \r\n" );
document.write( "\r\n" );
document.write( "Each of those 3!=6 orders in which they could be drawn\r\n" );
document.write( "has the same probability: \r\n" );

document.write( "P(R&B&Y) =  =  = \r\n" );
