Stat511: Statistical Methods Lab 2 Spring 2010 Due Thursday, April 29, 2010 1. Dice Experiment . Roll two dice 100 times. (a) [5 points] What is the probability of getting a total of 12 or an absolute diﬀerence of 4? Compare the probability with theoretical answer. (b) [5 points] What is the probability of getting at least one 6 or an absolute diﬀerence of 4? Compare the probability with theoretical answer. To do this experiment visit http://random.org/dice/ or http://www2.whidbey.net/ohmsmath/webwork/javascript/dice2rol.htm . 2. Cards Experiment . Draw 3 cards from a shuﬄed 13 deck of cards without replace- ment, repeat the process 99 times. (a) [5 points] What is the probability all three cards are not faces? Calculate the theo- retical answer. To do this experiment visit http://random.org/playing-cards/ or http://randomizer.org/ . (b) [5 points] Repeat the trial but this time with replacement. Compare the probability with theoretical answer. To do this experiment visit
