Question One: Provide an activity diagram, assuming the "Most Likely time value.

Question Two: What is the Critical Path for the above activity diagram?

Question Three: Provide a 1000 iteration monte-carlo simulation in Excel. We will use the PERT distribution for all of our randomly generated times. Please refer to the virtual office discussion. Provide the Excel file in your submission. Copy and paste a screen shot of your Excel file monte-carlo simulation in the Word submission document. You do not need to provide the complete simulation in the Word document just a screen shot of the first few rows of the model.
