QUESTION:

8. Consider a voted koon structure. The voting can be specified in two different ways:

   As the number k out of the n components that need to function for the system to function. As the number k of the n components that need to fail to cause system failure.

   In the first case, we often write koon:G (for good) and in the second case, we write koon:F (for failed). (a) Determine the number x such that a 2004:G structure corresponds to a xoo4:F structure. (b) Determine the number x such that a koon:G structure corresponds to a xoon:F structure.
