A project consists of 7 activities. The time for performance of each of the activities is a random variable with the respective probability distribution given here.

Now,

(a) draw the network diagram and identify the critical path using the expected activity times.

(b) simulate the project using random numbers to determine the activity times. Find the critical path and the project duration.

(c) repeat the simulation four more times. Is the same path critical in all the simulations?
