Please find below the question, and I need full explanation on the 3.1 part, where you need to seperate the answers as follow:

- Expected activity duration for each of the activities

- A project network (Activity on Node)

- Complete the forward and backward pass,

- Compute the activity slack

- Identity the critical path.

I shall be grateful if you could prepare a full new answer as i saw the answer for this question but it seems to be erroned.

Thanking you beforehand.
