Below you will find project activities and respective time estimates:

	Time Estimates
Activity	a	m	b	Predecessor
A	1	4	7	-
B	2	6	7	A
C	3	4	6	D
D	6	12	14	A

(a) Calculate expected time and variance for each activity

(b) Draw critical path (in your books, but do not submit here) and identify the Critical Path

(c) Calculate Early, Late, and Slack times for each activity

(d) What is the probability that the project can be completed in 34 weeks?
