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 (driver or rider) | 13,100 |
| Motorcycle (driver or rider) | 4,500 |
| Tornado | 553 |
| Skydiving | 56 |
a) What is the probability that an American chosen at random died as a passenger car occupant last year?
b) What is the probability that you died as a passenger car occupant last year?
d) What is the probability that an American chosen at random will die as the result of a tornado next year?
g) People sometimes claim skydiving is less dangerous than driving or riding in a car. Does the data support this claim? Explain.
h) People sometimes claim motorcycle riding is less dangerous than traveling by car. Does the data support this claim? What additional information and/or calculations would be useful to evaluate this claim?
