Using the information provided in the table, the network diagram and the expected project completion time = 39 weeks:

Activity		Optimistic Time (weeks)		Most Likely Time (weeks)		Pessimistic Time (weeks)
A		8		10		12
B		4		10		16
C		4		5		6
D		6		8		10
E		4		7		12
F		6		7		9
G		4		8		12
H		3		3		3

The critical path is A-B-D-G-H.

(Round your answers to 4 decimal places, e.g. 1.7582.)

(a) Calculate the probability of completing the project in 34 weeks.

P(project 34) =

(b) Calculate the probability of completing the project in 41 weeks.

P(project 41) =
