Refer to the Table 1 and do the following:

1. Calculate the Expected time, meantime.
2. Develop the Network diagram using the expected time and use PERT Analysis to know the mean and Sd of the project.
3. Based on these estimates and the resultant expected project duration of 69 days. Does the executive committee want to know what is the probability of completing the project before a scheduled time of 68 days?
4. How do you measure project risk exposure? Explain and propose ways to reduce the project risk exposure.
