Which concept describes the risk formula as a combination of two factors?

• A. Probability and Severity
• B. Probability and Frequency
• C. Consequence and Severity
• D. Probability and Consequence

Answer: (D)

Risk is viewed as a product of two factors: how likely the event is to occur and how large the harm would be if it does. By multiplying probability by consequence, you get a single risk score that rises with greater likelihood or with more severe outcomes. This captures both how likely something is and how bad it would be, which is the essence of risk assessment. Considering alternatives, combining probability with frequency mixes likelihood with how often the event happens rather than the damage per event. Pairing consequence with severity focuses only on the impact without weighing its likelihood. And pairing probability with severity, while close in spirit, uses severity instead of the specific term for the outcome’s impact, so the standard two-factor form is probability and consequence.
