Document Summary
Chapter 5 suggested problems: 1, 3, 9, 13, 25, 51, 57, 59, 65, 77. Problem 1: the probability that a wildcat well will be productive is 1/13. Assume that a group is drilling wells in various parts of the country so that the status of one well has no bearing on that of any other (independent). Problem 2: it has been found that 70% of all printers used on home computers operate correctly at the time of installation. What is the probability that at least 9 units operate correctly in each of the 5 months (i. e. january has at least 9 units, February also has at least 9 units, etc. Problem 3: load-bearing structures in underground mines are often required to carry additional loads while mining operations are in progress. As the structures adjust to the new weight small- scale displacements take place that result in the release of seismic and acoustic energy, called rock noise.
