You can put this solution on YOUR website! IF YOU HAVE 14 RED MARBLES, 16 BLACK MARBLES AND 10 GREEN MARBLES TOGETHER IN A BAG, WHAT IS THE PROBABILITY OF PICKING A RED MARBLE FROM THE BAG WITHOUT LOOKING? ~ PREVIOUS, I THINK
Chances of a Red and Chances of a Red
Chances of a Red * Chances of a Red
14/40 * 13/39 ~ (chances of a red)/(total chances left)
