c. Determine the critical path in the project network.
A-C-E-G V
d. What is the expected duration and variance of the critical path? If required, round your answer to two decimals.
Expected duration =
32 V
Variance =
2.16 V
e. What is the likelihood that the project will be completed within 30 days? If required, round your answer to four decimals. Note: Use Appendix B to identify the probability.
Likelihood =
