Answer 3

4 green, 3 red, 3 yellow marbles. what is the probability that you draw a red marble?

Answer 4

there are 3 red marbles, and a total of 4+3+3 = 10 marbles. therefore, the probability of drawing a red one on the first draw is 3/10, or 30%.

After you have drawn that red marble, and do not put it back in the bag, there are now 9 marbles: 2 red, 3 yellow, 4 green. What is the probability at this point that you draw a yellow marble from the bag?
