# Math Help - Applied statistics

1. ## Applied statistics

The probability is 1 in 4,000,000 that a single auto trip in the U. S. will result in a fatality. Over a lifetime, an average U. S. driver takes 50,000 trips.

A. What is the probability of a fatal accident over a lifetime? explain reasoning carefully. Assume independent events.

B. Why might the assumption of independence be violated?

C. Why might a driver be tempted not to use a seat belt "just on this trip?"
