: The probability is 1 in 4,000,000 that a single auto trip in the United States 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 your reasoning carefully. Hint: Assume independent
events. Why might the assumption of independence be violated? (b) Why might a driver be
tempted not to use a seat belt �just on this trip�? This question is from textbook

50,000/4,000,000=.0125 OR 1.25% PROBABILITY THAT THIS PERSON WILL HAVE A FATAL ACCIDENT.
THIS ASSUMES THAT THE PERSON DRIVING 50,000 TRIPS IS CLOSE TO THE AVERAGE LENGTH OF THE TRIPS USED IN THE STUDY OF THE 4,000,000 TRIPS.
SPEED, DAY VS. NIGHT DRIVING, SEAT BELT USE, DRIVING DRUNK, LONG DISTANCE DRIVING AND AGE MAY HAVE A MAJOR IMPACT ON THESE STATS.
