PERT Questions calculation
Anybody, please point me to some book/notes for the calulation of PERT. I know it is easy for some people
but I reeally need to understand how to calulate these PERT related questions easily and fast.
For example, In the following quesiton, the answer is 50%. How you calculate this? Do you need to perform
some calulations or you just use Normal Distribution 'bell-shaped' curve? I just dont understand this
Normal distribution 'bell shaped' curve and need to learn how to calulate this instead of looking at the curve
Or In the following question, the answer is 84.1%, how you calculate this?
