Problem 53E: Chapter: CH6 Problem: 53E Refer to Exercise. Suppose that three people are selected at random. a. Draw a probability tree to depict the experiment. b. If we use the notation RRR to describe the selection of three right-handed people, what are the descriptions of the remaining seven events? (Use L for left-hander.) c. How many of the events yield no right-handers, one right-hander, two right-handers, and three right-handers? d. Find the probability of no right-handers, one right-hander, two right-handers, and three right-handers. Exercise Approximately 10% of people are left-handed. If two people are selected at random, what is the probability of the following events? a. Both are right-handed. b. Both are left-handed. c. One is right-handed and the other is left-handed. d. At least one is right-handed
