[3 marks] (c) Show the activity schedule (ES, EF, LS, and LF) as well as slack (in table). [5 marks] (d) Determine and state the critical path for this project. This must be based on your work in (c) and not by inspection. [2 marks] (e) What are the expected time and the variance of the project? [2 marks] (f) What is the probability the project will be completed in less than 32 weeks? [3 marks]
