Probability and Severity are the two factors determine the risk level in the Risk Assessment Matrix.

Risk projection, also called risk estimation, attempts to rate each risk in two ways-the likelihood or probability that the risk is real and the consequences of the problems associated with the risk, should it occur. The project planner, along with other managers and technical staff, performs four risk projection activities: (1) Establish a scale that reflects the perceived likelihood of a risk, (2) Delineate the consequences of the risk, (3) Estimate the impact of the risk on the project and the product, and (4) Note the overall accuracy of the risk projection so that there will be no misunderstandings
60, 72, 84, 90 and 96 each have twelve factors.
There are no specific quantitative values for the separate parts of the First Trimester screen. (Double Marker Test). This is a screening too, used to assess risk factors. The test is most accurate between the 16th week and the 18th week and the correct fetal age is mandatory for accurate testing. The blood screen measures two pregnancy related hormones: hCG and PAPP-A. The ultrasound evaluation measures nuchal translucency (fluid beneath the skin behind baby's neck). You will be told whether your results are "normal or abnormal", and you will be given a risk level by your genetic counselor/OB. The counselor will give you your risk factor for chromosomal abnormalities based on the test results (for example 1/250, 1/1300). A positive test means that you have a 1/100 to 1/300 chance of experiencing one of the abnormalities. Using a maternal blood screening test with an ultrasound evaluation of the fetus to identify risk for specific chromosomal abnormalities, including Down's Syndrome Trisomy-21 and Trisomy-18. When the test results come back in the typical range, this result reduces the woman's risk of having a child with Down syndrome. If the woman is 25, this decreases her risk from 1/1100 to 1/4400. If the woman is 35 years old, this decreases her risk from 1/250 to 1/1000. If the woman is 45, it decreases her risk from 1/20 to 1/80. 85 out of 100 babies affected by the abnormalities the screen tests for will be identified. 5% of the tests will be false positive.
