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.

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.
At an intersection, there are two accidents per day, on average. What is the probability that after the next accident there wll be no accidents at all for the next two days?
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...
Note: Use statistical tables when it is possible The number of accidents at an intersection follows Poisson distribution with an average of three accidents per day. Find (Round to THREE decimal places) 1. The probability of an accident-free day. 2. The probability that there is at most 14 accidents in five days. 3. The accepted number of accident-free days in January 4. The probability that there are four accident-free days in January Calculate and 2 ? 5. Suppose you are...
3. Th e factory has experienced an average of four accidents per month over the last three years. The manager decided to require each employee to attend an accident prevention workshop. a. Assuming that the workshop has no effect on the accidents rate, what is the probability that next month there will be at least four accidents? Suppose that next month there is only one accident. Would you conclude that the workshop was successful? (Source: Brightman, H., & Schneider, H....
On averago, 5 traffic accidents per month occur at a certain intersection. Complete parts (a) through (c) below. Click here to view the table of Poisson probability sums (a) What is the probability that exactly 6 accidents will occur in any given month at this intersection? The probability that exactly 6 accidents will occur in any given month at this intersection is 0.1462 (Round to four decimal places as needed.) (b) What is the probability that fewer than 5 accidents...
(1 pt) The number of accidents that occur at a busy intersection is Poisson distributed with a mean of 4 per week. Find the probability of the following events. A. No accidents occur in one week Probability B. 5 or more accidents occur in a week. Probability- C. One accident occurs today. Probability
The number of accidents that occur at a busy intersection is Poisson distributed with a mean of 3.5 per week. Find the probability of the following events. A. No accidents occur in one week Probability - B. 8 or more accidents occur in a week. Probability - C. One accident occurs today. Probability-
The number of accidents that occur at a busy intersection is Poisson distributed with a mean of 3.1 per week. Find the probability of the following events. A. No accidents occur in one week. Probability = B. 5 or more accidents occur in a week. Probability = C. One accident occurs today. Probability =
