Question 3

Question 4

Three sequential activities A, B, and C have optimistic, most likely, and pessimistic durations as follows: A: $o=3,m=5,p=9$ days; B: $o=2,m=4,p=6$ days; C: $o=1,m=3,p=5$ days. Assuming they form the critical path, what is the expected project duration $T_E$?

Question 5

Using the same activities in the previous question, what is the variance $\sigma^2$ of the project duration?
