Veronica, Program Office Director, has developed the tasks, durations, and predecessor relationships in the following table for renovating hospital Emergency Rooms. To solve this problem, calculate the expected completion time and variance for each activity, draw a network diagram, complete a forward and backward pass, identify the critical path. Follow the step-by-step solution approach in Gido and Clements text, Chapter 5, Appendix 1 called Probabilistic Activity durations. What is the probability of completion of the project before week 36?
