There is an average of four accidents per year at a particular intersection. What is the probability of more than one accident there next month? Hint: Use 1 month = 1/12 of a year to first get the number of accidents that are expected next month.
Homework Answers
Average rate = 4 per year
So, average rate = (4/12) per month = (1/3) per month.
This is Possion distribution because we have average value given.
Hence, probability of more than one accident in next month is 0.0446.
Answer is rounded to 4 decimal places.
Please comment if any doubt. Thank you.

Suppose traffic accidents at a road intersection occur once every 7 days. It can be assumed there is no more than 1 accident occurring at this intersection simultaneously, and at this intersection accidents can occur at any time. Also, an accident is not due to other accidents. (What type of distribution is this i.e. Gaussian, Poisson, etc.?) What is the probability that there are 3 accidents during the next 15 days at the intersection? Calculate by hand. What is the...

The number of accidents per week at a busy intersection was recorded for a year. There were 19 weeks with no accidents, 17 weeks with one accident, 9 weeks with two accidents, and 7 weeks with three accidents. A week is to be selected at random and the number of accidents noted. Let X be the outcome. Then X is a random variable taking on the values 0, 1, 2, and 3. (a) Write out a probability table for X...
