3(b). The following data relates to the activities required for
a project. Since exact duration for each activity is not known for
certain, three time estimates were made, namely: - the optimistic,
most likely and pessimistic time estimates. The precedence
relationships are also shown in the data below. You will need to
analyze this problem using what you learned in Chapter 18 of...
