Below is a project with tasks, predecessor relationships, and deterministic durations (in weeks). Calculate the project duration. (Yes, this is a bit of a review from previous weeks). Activity PrecedentDuration in weeks A 1 B A 2 2 D A 6 E A 4 F C,D,E 1 Below is the same project from the prior question with tasks, predecessor relationships, and durations (in weeks). All activities save for D have deterministic durations, but now activity D's duration has some variability associated with it: the most likely duration is 6 weeks, but it could be done as early as 3 weeks or as late as 7 weeks. All other activities' durations remain unchanged and do not have any variability. Calculate the expected duration of the project to 2 decimal places.

All activities save for D have deterministic durations, but activity D's duration has some variability associated with it: the most likely duration is 6 weeks, but it could be done as early as 3 weeks or as late as 7 weeks. Calculate the standard deviation of the critical path's duration to two decimal places. Activity Precedent Duration in weeks > 1 B A 2 C B 2 D A see above E A 4 | F C,D,E 1 Answer: Calculate the probability that we will finish the darn project we've been working with for most of this quiz by 9 weeks. Express your answer either as decimal, like 0.123 or a percentage, like 12.3% (but leave the % in). Our last question will be hand-graded by me, and I will give you full credit if you miscalculated one of the earlier parts but otherwise do everything correctly, if I can follow your work (should you upload it) and it makes sense. (It also means I won't be releasing quiz scores until later tomorrow morning)
