Which two considerations are used to calculate risk for the Marine Corps Operational Risk Assessment?

• A. Probability of occurrence and exposure
• B. Frequency and duration
• C. Probability of occurrence and severity
• D. Impact and complexity

Answer: (C)

In the Marine Corps Operational Risk Assessment, risk is determined by how likely a hazard is to occur and how severe the consequences would be if it does. The standard calculation combines probability of occurrence with severity to produce the risk level shown on the ORM matrix. This is why pairing probability with severity is the best choice: it directly reflects the likelihood and impact of a hazard. Factors like exposure, frequency, duration, or complexity aren’t used to calculate the basic risk rating in the ORM framework, though they can influence planning and the controls you apply to reduce risk.
