Each of k jars contains m white and n black balls. A ball is randomly chosen from jar 1 and transferred to jar 2, then a ball is randomly chosen from jar 2 transferred to jar 3, etc. Finally, a ball is randomly chosen from jar k. Show that the probability that the last ball is white is the same as the probability that the first ball is white, i.e., it is m/(m+n) . (Hint: Prove the result for K=2...

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)
