Question

bag has 2 green marbles, 3 red marbles, and 3 yellow marbles. What is the probability that you pick a red marble, do not replace it, and pick yellow marble?

Answer 1

Ok.. so there is a total of 8 marbles. its a 3 out of 8 chance that you would get a red marble, when you do get it, you dont replace it so there is now a total of 7 marbles. Then you want a yellow marble so that is now 3 out of 7 chance.
(3/8)*(3/7) = is about 16% chance

Answer 2

P(red) then P(yellow)
3/8 * 3/7 = 9/56
