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.
