A project network is shown in the figure. @ Use a forward and a backward pass to determine the critical path, and then fill out the following table. Activity times are in weeks. (For the precedence activities, enter your answers as comma- separated lists. If an activity does not have immediate predecessors, enter NONE.)

Is the probability of being finished in fewer than 27 weeks more or less than 50%7? O The probability is more than 50% because 27 weeks is more than the expected time for the project. O The probability is less than 50% because 27 weeks is less than the expected time for the project. O The probability is more than 50% because 27 weeks is less than the expected time for the project. The probability is less than 50% because 27 weeks is more than the expected time for the project. X
