Probability of choosing balls from a bag
WebbWe need to remember here that we are drawing these without replacement. The probability of drawing red on the first draw is 15 out of 21. But if we take one ball away and we do not replace it, then, on our second draw, we’ll only have 20 balls to choose from. And if we’re going to choose a blue ball from that 20, there are six remaining ...
