Gce Model Questions Vol1 2018 Geography Question 1
Practice objective / multiple choice question 1 from the 2018 Gce Model Questions Vol1 Geography examination.
A region is exposed to three types of environmental hazards: flood, earthquake and landslide. The monetary loss per event is £(200{,}000) for a flood, £(150{,}000) for an earthquake and £(100{,}000) for a landslide. Let the annual probabilities of occurrence be (p) (flood), (q) (earthquake) and (r) (landslide). The expected annual loss is £(120{,}000). It is known that the flood contribution to the total loss is twice that of the earthquake, and that the landslide probability is half the flood probability. Calculate the annual probability (p) of a flood (expressed as a decimal to three significant figures).
