6A. Draw the Network Diagram, and identify and discuss the project duration and the critical path using the following activity notation:
the first pic:
First: Draw the precedence diagram.
Second: Using the notation given identify the duration of the project: you can type it.
Third: identify the critical part and explain the critical path.
Fourth: Explain your answer. This can be done by describing the process and the observations done once the answer has been found.
