The number of traffic accidents on the day of the first snow
fall in a small town follows a Poisson distribution with an average
of 8.9 traffic accidents over a 24 hour time period. A) What is the
probability that on the next first snow day there are more traffic
accidents than average? Show your work. B) After the first
accident, what is the probability that there are more than 3 hours
before the second accident occurs? Show your work. C) What is the
expected number of accidents on the first day? What is the most
likely number of accidents on the first snow day? Explain the
difference in those two answers.
