fishermen is 0.0012. Suppose two fishermen are
selected at random. Find the probability that both fishermen will
be fatally injured during the
year. Also, find the probability that exactly one will be fatally
injured during the year.

According to the most recent data from the Insurance Research Council, 16.1% of motorists in the United States were uninsured in 2010 (virginiabeach.injuryboard.com). Suppose that currently 16.1% of motorists in the United States are uninsured. Suppose that two motorists are selected at random. Let x de- note the number of motorists in this sample of two who are uninsured. Construct the probability distribu- tion table of x. Draw a tree diagram for this problem.
