probability that there will be two or fewer accidents during one week. (b) Calculate the probability that there will be two or fewer accidents in total during a period of 2 weeks. (c) Calculate the probability that there will be two or fewer accidents each week during a period of 2 weeks. (d) The company is shut fo
A multinational company operates factories around the world. Assume that the total number of serious accidents that take place per week follows a Poisson distribution with mean 2. We assume that the accidents occur independently of one another
(a) Calculate the probability that there will be two or fewer accidents during one week.
(b) Calculate the probability that there will be two or fewer accidents in total during a period of 2 weeks.
(c) Calculate the probability that there will be two or fewer accidents each week during a period of 2 weeks.
(d) The company is shut for two weeks for seasonal celebrations and therefore, over a whole year, the number of accidents follows a Poisson distribution with mean 100. Using a suitable approximation, calculate the probability that there will be more than 120 accidents in one year.
