  2. DISTRIBUSI PROBABILITA DISKRIT • National Oil Company conducts exploratory oil drilling operations in the southwestern United States. To fund the operation, investors form partnerships, which provide the financial support necessary to drill a fixed number of oil wells. Each well drilled is classified as a producer well or a dry well. Past experience in this type of exploratory operation shows that 15% of all wells drilled are producer wells. A newly formed partnership has provided the financial support for drilling at 12 exploratory locations. • What is the probability that all 12 wells will be producer wells? • What is the probability that all 12 wells will be dry wells? • What is the probability that exactly one well will be a producer well? • To make the partnership venture profitable, at least three of the exploratory wells must be producer wells. What is the probability that the venture will be profitable?
