Company ABC needs to execute the following project:

Predecessor(s)	Expected Duration	Task
-	5	A
-	10	B
A	20	C
A,B	13	D
C,D	10	E
A,B	25	F
E,F	8	G

1. Assume that all task durations are deterministic. Without using a simulation, what is the expected duration of the project? Show your calculations.

For b and c assume that each task is normally distributed with the given expected duration. The standard deviation of each task is 30% of its expected duration (for example, the standard deviation of task A is 1.5).

2. Using a simulation with 1000 trials, what is the expected duration of the project? What is the expected standard deviation?
3. What is the probability that the project would be completed within 43 days?
