A hazardous waste site will develop small repairable leaks on average of once every 5 years. When the 10th leak occurs, the dumb is considered unusable and will be immediately closed. Assume th occurrence of leaks is a beenoulli sequence. a. compute the probability that exactly 3 leaks will occur in 10 years. b. compute the probability of having fewer then 3 leaks in 10 years. c. when is the first leak expected? d. what is the expected number of...
4. The most dangerous intersection in California is the crossing of Devonshire Street and Reseda Boulevard in Los Angeles. On average, an accident occurs at this intersection once every six days. The city labels a day an "Unacceptable" if there are 2 or more accidents in a given day. After 10 Unacceptable days, the city will shut down the intersection. [4 points] a. How long, in days, do you expect the intersection will be open? (You must define any random...
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...
A plant has a pollution-control system shutdown once every 75 days, on average. What is the probability of at least one shutdown in the next year? 100.0% 1.33% 98.6% 99.3%
I construction work on multistorey building is a potentially hazardous occupation. A building contractor who is building a skyscraper at a steady pace finds that in spite of a strong emphasis on safety measures, he has been experiencing accidents among his large group of steel workers; on the average, about l accident occurs every 6 months. ()Assuming that the occurrence of a specific accident is not influenced by any previous 4.4 Stee accident, find the probability that there will be...
Suppose that it snows in Greenland an average of once every 27 days, and when it does, glaciers have a 30% chance of growing. when it does not snow in Greenland, glaciers have only a 5% chance of growing. What is the probability that it is snowing in Greenland when glaciers are growing? (Round your answer to four decimal places.)
Suppose that it snows in Greenland an average of once every 29 days, and when it does, glaciers have a 27% chance of growing. When it does not snow in Greenland, glaciers have only a 5% chance of growing. What is the probability that it is snowing in Greenland when glaciers are growing? (Round your answer to four decimal places.)
rain occurs randomly and independently with an average of 31 days per year. a) what is the probability of more than five rainy days in the next 2 months? b) what is the probability of three rainy days next month?
Suppose that it snows in Greenland an average of once every 21 days, and when it does, glaciers have a 26% chance of growing. When it does not snow in Greenland, glaciers have only a 9% chance of growing. What is the probability that it is snowing in Greenland when glaciers are growing?
