Likelihood and impact describe the same feature of a risk scenario.

### Why this is right Likelihood concerns how probable a harmful event is, while impact concerns how serious its effects would be. Because they measure different features, they are not interchangeable. ### The concept A scenario can be unlikely but have severe consequences, or likely but have limited consequences. Considering both gives decision-makers a more useful picture than relying on only one. Controls and reassessment then help determine how much risk remains. ### The other options - **True**: This incorrectly treats probability and severity as the same measure. It is tempting because both contribute to a risk rating, but they answer different questions. ### Terms - **Likelihood**: How probable a harmful event is. - **Impact**: The severity of the effects if harm occurs. ### Remember Ask “How likely?” and “How bad?” as separate questions.
