To Calculate the Probability of Completing a Project by a Certain

question 64

Multiple Choice

To calculate the probability of completing a project by a certain date,

• A) the expected completion time of the project is taken to be the sum of the activity times on the shortest path.
• B) the variance of the distribution of project completion times is taken to be one-sixth the difference between the latest finish time and the earliest finish time of the last activity in the project.
• C) we assume that the activity durations are independent of each other so that the normal distribution can be used.
• D) we only need the parameters of the beta distribution for the finish node of the diagram.
