![Question 1:
Identify normal, abnormal and negative scenarios for the library system (see the case study description
in Section 1.1.2).
Question 2:
Using the risk tree shown in figure 1, derive a cut-set tree similar to figure 2, then based on it generate a
cut set of the given risk tree.
Note:
Expected outcome: cut-set tree, and cut set.
Make sure to use the exact initial (CBFD, CM, .. etc.) as shown in each leaf when building cut-set
tree and cut set or risk tree. Otherwise you will lose points.
