Question

Lola pulls two marbles from a bag containing four red marbles, four blue marbles, and 12 yellow marbles without replacing them. What is the probability that she pulled out a red marble first and a yellow marble second? Express your answer in decimal form, rounded to the nearest hundredth.

Answer 1

Okay so first since there are 4 red marbles, 4 blue marbles, and 12 yellow marbles, you add them together so the whole total would be 20 marbles now. Since there are 4 marbles, the probability of her pulling it out would be 4/20. So now that she took 1 red marble away, we have 19 marbles left. So now that has been finished, she 1 more yellow marble away so now we have 12/19. Now that it's completed you multiply the two, and now you should have 12/95, divide 12/95 and you'll get 0.126315789 in other words rounded that too the nearest hundredth and you'll get 0.13
