7. True or False To say that events A and B are independent means that P(A|B) = P(A). A. True B. False Slide 5 - 7 © 2013 Pearson Education, Inc. Response Counter

8. True or False To say that events A and B are independent is to day that the knowledge that event B occurred does not change the probability of event A occurring. A. True B. False Slide 5 - 8 © 2013 Pearson Education, Inc. Response Counter

11. True or False The Law of Large Numbers states that if an experiment with a random outcome is repeated a large number of times, the empirical probability of an event is likely to be close to the true probability. A. True B. False Slide 5 - 11 © 2013 Pearson Education, Inc. Response Counter
