This problem is from chapter- Project Scheduling. Please show full work. Also, please do not copy the wrong amswer from somewhere else. I already lost one question due to that. This is my 2nd attempt.

2. For the activity on arrow network information given below (activity durations are given in the table under part b): a. Compute the earliest event occurrence time (TE;), the latest allowable event occurrence time (TLj), and the event slack (ES)) for all nodes/events.
