Distinguished expert, please focus on the third question. I am not very grateful to you for your service. That's the problem.A project is made of the following activities:

Complete the table above $-$ ES$,$ EF$,$ LS$,$ LF$,$ Slack $(15$ points$)$

What is the critical path? What is the project duration? $(5$ points$)$

Refer to the critical path you found in $2.$ Assume that every activity is normally

distributed. Each activity's mean is given in the table above. Each activity's standard

deviation is $20\%$ of its mean $($for example, the mean duration of activity A is $2$ and its

standard deviation is $0\mathrm{.}4).$ What is the probability that the project will last more than $48$

days? $(10$ points$)$
