Q3 A Probability and Impact Matrix contains risks prioritized according to their potential implications for meeting the project's objectives. The typical approach is: A. To use a look-up table or Probability and Impact Matrix with specific combinations of Probability and impact that lead to a risk being rated as "high", "moderate" or "low" importance. The importance for planning responses to the risk are usually set by the organization. B. To create a Risk Breakdown Structure with the probabilities and Impacts listed on the individual boxes. The higher the risk, the closer it is towards the Start Node. C. To use a look-up table or Probability and Impact Matrix with specific combinations of Probability and impact that lead to a risk being rated as "high", "moderate" or "low" importance. The importance for planning responses to the risk are usually set by the project manager. D. To create a matrix with the Cost, Time, Scope and Quality on one axis and probability of occurrence on the other. You are attempting to estimate the resources required to put the server racks together in the new data center you are building. It has occurred to you that you may be able to compress the schedule if you look at using power tools vs. hand tools to build the racks and use individuals who have worked on this brand of rack in the past. This is an example of what type of resource estimating tool? A project is contracted as a Time & Material (T&M) type of contract. The service provider initially estimates that the total effort involved would be about 1000 hours of effort. The project is contracted at a rate of US$ 75 per hour of effort. If the project ended up with 1200 hours of effort, what would the contract payout be
