Practice objective / multiple choice question 6 from the 2021 Gce Model Questions Vol1 Geography examination.
A region is exposed to three environmental hazards: A, B and C. The probability of occurrence per year and the impact rating (on a scale of 1-10) are: Hazard A - probability 0.02, impact 8; Hazard B - probability 0.05, impact 6; Hazard C - probability 0.01, impact 9. Mitigation measures reduce the risk of Hazard A by 20 % and Hazard C by 30 %. If the total post‑mitigation risk (defined as \( \text{risk}=p \times \text{impact} \times (1-\text{mitigation})\)) must equal 0.40, what mitigation percentage (to the nearest whole percent) must be applied to Hazard B?
