a) If the company requires a markup of 25%, what should be the total price charged for a normal [standard] project?
b) Examine and discuss PRTI's decision to propose a potential client to upgrade its server for a total amount of $50,000, completed in 31 days.
c) A key member of the project, recommended to the project manager to study the uncertainties exhibited in prior similar projects.
The project management gathered the information and found that the duration of six of the tasks could be modeled as Beta distributions.
Based on the following information (without "crushing"), what is the probability that a project could be completed between 30 and 38 days?
