Gce Model Questions Vol1 2021 Geography Question 23
Practice objective / multiple choice question 23 from the 2021 Gce Model Questions Vol1 Geography examination.
A coastal region experiences two types of environmental hazard each year: floods and landslides. The probability of a flood in any given year is 0.12 with an average economic loss of £3 million per flood. The probability of a landslide is 0.05 with an average loss of £5 million per landslide. Two mitigation options are available: - A flood barrier that reduces flood loss by 40 % at a cost of £1 million. - Slope stabilisation that reduces landslide loss by 60 % at a cost of £2 million. If only one mitigation measure can be implemented, which option gives the greater reduction in expected annual loss per £ spent?
