The average number of acres burned by forest and range fires in a large county is 4,200 acres per year, with a standard. deviation of 800 acres. The distribution of the number of acres burned is normal. Compute the probability that more than 5,000 acres will be burned in any year. Determine the probability that fewer than 4,000 acres will be burned in any year. What is the probability that between 3,500 and 4,100 acres will be burned? In those years when more than 5,500 acres are burned, help is needed from eastern-region fire teams. Determine the probability help will be needed in any year. a. The probability that more than 5,000 acres will be burned is (Round to four decimal places as needed.) b. The probability that fewer than 4,000 acres will be burned is (Round to four decimal places as needed.) c.
