1) Confirm that the table does give a probability distribution for the experiment.
The sum of the percent is ....% therefore this does give a probability distribution.
2) Explain the probability that a U.S. user who downloads music, selected at random, acquired it from either the United States or Canada?
3) Explain what is the probability that a U.S. user who downloads music, selected at random, does not obtain it from Italy, the United Kingdom (U.K.) or France?
