Consider the hazard of icy roads posing a risk of a car crash. Construct the two-factor risk equation for this hazard.
risk = probability(crash) * severity(crash)
A more detailed equation breaks down the risk into hazard level, exposure, and vulnerability. Describe a measure we might take to reduce each of these factors.
We could reduce the hazard level by putting grit on the roads. We could reduce exposure by minimising the amount of driving we do in icy conditions, i.e. only driving if it’s essential. We could reduce vulnerability by ensuring the car has appropriate safety features and always wearing a seatbelt, for example.
