There are five urns, each containing 10 white and 15 red balls. A ball is drawn at random from the first urn and put into the second one. Then a ball is drawn at random from the second urn and put into the third one and the process is continued. By simulation, determine the approximate probability that the last ball is red. Answer: 0.6.
