The number of road accidents at a certain traffic roundabout has been found to follow a Poisson distribution with a mean of 0.8 accidents per week. What is the probability that: (a) there will be at least 2 accidents in a particular week? (3 marks) (b) there will be exactly 3 accidents in a particular 3-week period? (3 marks)

The number of accidents that occur at a busy intersection is Poisson distributed with a mean of 3 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 =

An automobile manufacturer is concerned about a fault in the braking mechanism of a particular model. The fault can, on rare occasions, cause a catastrophe at high speed. The distribution of the number of cars per year that will experience the catastrophe is a Poisson random variable with $\lambda=5$. (a) What is the probability that at most 3 cars per year will experience a catastrophe? (b) What is the probability that more than 1 car per year will experience a catastrophe?
