Solved: An urn contains two blue balls (denoted B1 and B2)
Chapter 9, Problem 9.22(choose chapter or problem)
An urn contains two blue balls (denoted B1 and B2) and one white ball (denoted W). One ball is drawn, its color is recorded, and it is replaced in the urn. Then another ball is drawn, and its color is recorded. a. Let B1W denote the outcome that the rst ball drawn is B1 and the second ball drawn is W. Because the rst ball is replaced before the second ball is drawn, the outcomes of the experiment are equally likely. List all nine possible outcomes of the experiment. b. Consider the event that the two balls that are drawn are both blue. List all outcomes in the event. What is the probability of the event? c. Consider the event that the two balls that are drawn are of different colors. List all outcomes in the event. What is the probability of the event?
