. . Why? 3. Describe the differences and similarities between the cone of uncertainty and rolling wave planning 4. Create a precedence diagram based on the following information: There are ten total tasks, named A-J. Tasks A, B, and H have durations of two days. Tasks C, E, I, and J have durations of three days. Tasks D, F, and G have durations of one day. Tasks A, B, and D can be conducted in parallel. Task C must precede task B. Tasks A and F must precede Task E. Task E must precede Task G. Tasks B and D must precede Tasks H and I, respectively. Tasks G, H, and I may be conducted in parallel. Tasks G, H, and I precede Task J
