14. For a project comprising activities A, B, ... , H, the following information is available:

Precedence Relationships:

A and B are the first activities of the project. C succeeds A while B precede D. Both C and D precede E and F. Activity G follows activity Fwhile His the last activity of the project and succeeds E and G.

Time Estimates and Probabilities:

Simulate the project and determine, using random numbers, the activity times. Find the critical path and the project duration. Repeat five times. Does the critical path change? State the estimated duration of the project in each of the trials.
