Best ResponseYou've already chosen the best response.0If you take out a red and don't replace it then you now have 4 green, 2 red, and 2 yellow. Probability is the part over the whole. So it's 2 yellow/ 8 = 1/4. ... now I'm confused. That's not an answer choice.

Best ResponseYou've already chosen the best response.1A bag has 4 green marbles, 3 red, and 2 yellow. What is the probability that you pick a red marble, do not replace it, then pick a yellow marble? First find the total: 9 marbles. There's 3 reds. Chance of picking a red is thus 3/9. Since we don't replace it, there's now only 8 remaining marbles. There are 2 yellow, so the chance of picking a yellow is 2/8. To find the probability of picking a red and then a yellow, multiply those two probabilities together:\[\frac{ 3 }{ 9 } \times \frac{ 2 }{ 8 } = \]

Best ResponseYou've already chosen the best response.0It's the probability of doing the two actions in succession. That's why I was wrong.

Best ResponseYou've already chosen the best response.1But that gives 1/12, which also isn't an answer choice... even though I'm pretty sure that's the correct solution.
