I am just confuse on how to compute the Standard Deviation for this problem. Plz help me.
I have to compute Standard Deviation for each line and that is where I dont know get it what to do.
So if some one can show me even how to do SD for "Activity" A then I can do rest.
Activity Immediate Predecessor---Optimistic Time--Most Likely Time--Pessimistic
A --------------------------------------10----------- 22---------------22
