P 3 10 7 9 2 8 p 7 120 since we were ask to find the probability of chosing 1 red 1 black and 1red marble without replacement after each draw we can use the fundamental method in finding the probability.
However you re told that each of the labels are wrong.
Are the events red black and yellow mutually exclusive.
Sampling from the box with replacement will return a black marble frac13 of the time.
