## Questions

The table below shows the number of deaths in the U.S. in a year due to a variety of causes. For these questions, assume these values are not changing from year to year, and that the population of the United States is 312 million people.

Cause | Deaths |
---|---|

Passenger car occupant | 13,100 |

Motorcycle driver | 4,500 |

Tornado | 553 |

Skydiving | 56 |

- What is the probability that an American chosen at random died as a passenger car occupant last year?
- What is the probability that
*you*died as a passenger car occupant last year? - What is the probability that
*you*will die as a passenger car occupant*next year*? - What is the probability that an American chosen at random will die as the result of a tornado next year?
- What is the probability that
*you*will die as the result of a tornado next year? - Why is this answer different than your answer to the previous question?
- People sometimes claim skydiving is less dangerous than driving. Does the data support this claim?
- People sometimes claim motorcycle riding is less dangerous than driving. Does the data support this claim? What additional information and/or calculations would be useful to evaluate this claim?

Make sure your numerical answers are accurate to at least 2 significant figures (values after leading zeros).
