In risk assessment methodologies, a likelihood scale evaluates the probability of a threat event occurring, while an impact scale assesses the severity of the resulting harm.

### Why this is right The stated likelihood values are 1 (Very Low), 2 (Low), 3 (Moderate), and 5 (Very High). The material does not list 4 as a level, so the claim that the displayed scale includes 4 for High is false. ### The concept A likelihood scale gives categories for judging how probable a threat event may be. Do not fill gaps or infer categories that are not specified in the assessment scheme. The course material separately gives impact labels of High, Moderate, and Low, so likelihood labels and impact labels should not be confused. ### The other options - **True**: This would be correct only if the supplied likelihood scale listed 4 as High, which it does not. ### Terms - **Likelihood scale**: A set of categories used to rate the chance of an event. ### Remember Use the values given in the scale: 1, 2, 3, and 5.
