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?"
Help, please....
