Below is an AOA diagram that includes the optimistic, most likely, and pessimistic time estimates $($in days$)$ for each activity. However, we just found out that a mistake was made and that activity $4-6$ should have the following values associated with it: $1-6-16.$ Use this information and the diagram to answer the question below. What is the expected duration of the project?

I have an answer but I$\text{'}$m not sure it's correct. I want to verify it$.3.$ Below is an AOA diagram that includes the optimistic, most likely, and pessimistic time estimates $($in days$)$ for each activity.

Expected duration: $20$
