You are constructing a probability/impact risk rating matrix for your project. Which of the following is true?

A. The PI matrix multiplies the risk’s probability by the cost of the impact to determine an expected value of the risk event.

B. The PI matrix multiplies the risk’s probability scales, which fall between 0.0 and 1.0, and the risk’s impact scales to determine a risk score.

C. The PI matrix multiplies the risk’s probability by the expected value of the risk event to determine the risk impact and assign a risk score based on a predetermined threshold.

D. The PI matrix multiplies the risk’s probability scales and the risk’s impact scales, which fall between 0.0 and 1.0, to determine a risk score.
