\n" );
document.write( "29 marbles: 8 green, 9 red, 5 yellow and 7 blue
\n" );
document.write( "4 drawn at the same time
\n" );
document.write( "P(all four marbles are the same color) = 8C4/29C4 + 9C4/29C4 + 5C4/29C4 + 7C4/29C4 
\n" );
document.write( "P(none of the marbles is red) = 1 - P(all red) = 1 - 9C4/29C4
\n" );
document.write( "P(one marble of each color) = 8C1*9C1*5C1*7C1/29C4
\n" );
document.write( "P(more than 2 yellow marbles) = 29C1*5C3/29C4 + 5C4/29C4 \n" );
