Which term is an approximation of the likelihood of a hazard scenario occurring; one component of risk?

• A. Hazard
• B. Risk
• C. Residual Risk
• D. Probability

Answer: (D)

Understanding risk involves two parts: how likely a harmful event is to occur and how severe the impact would be. The term that represents that chance is probability. It’s an estimate of the likelihood, often expressed as a percentage or a rate per year, because we base it on data and models and can’t know the future with certainty. This makes probability the best fit for describing the likelihood component of risk, while risk itself combines that likelihood with the potential consequences to describe overall exposure. The other terms describe different ideas: a hazard is the source of potential harm; risk is the overall chance of harm considering both likelihood and impact; residual risk is what remains after controls are applied.
