A cookie jar has 3 red marbles and 1 white marble. A shoebox has 1 red marble and 1 white marble. Three marbles are chosen at random without replacement from the cookie jar and placed in the shoebox. Then 2 marbles are chosen at random and without replacement from the shoebox. What is the probability that both marbles chosen from the shoebox are red?
1. A jar contains 3 black and 2 white marbles. We continue to draw marbles one at a time until two black marbles are drawn. If a white marble is drawn, the outcome is recorded, and the marble is put back in the jar before drawing the next marble. What is the probability that we will get exactly two black marbles in at most three tries? Do this problem using a tree diagram! (2 marks)

A jar contains black and white marbles. There are four more black marbles than white marbles. Two marbles are drawn from the jar at random. If the probability that the two marbles are the same color is equal to the probability that the two marbles are different colors, how many marbles are in the bag?
Two marbles are drawn randomly one after the other without replacement from a jar that contains 3 red marbles, 9 white marbles, and 3 yellow marbles. Find the probability of the following events. (a) A red marble is drawn first followed by a white marble. The probability is : 27/210 (b) A white marble is drawn first followed by a white marble. The probability is : 72/210 (c) A yellow marble is not drawn at all. The probability is :...
