Neco Model Questions Vol1 2021 Geography Question 26
Practice objective / multiple choice question 26 from the 2021 Neco Model Questions Vol1 Geography examination.
In a coastal district, two major environmental hazards are floods and landslides. The risk rating for a hazard is defined as the product of its annual probability of occurrence (as a decimal) and its average monetary impact (in millions of naira). The average impact of a flood is \(120\) million and that of a landslide is \(80\) million. It is known that the flood risk rating is twice the landslide risk rating. Moreover, the probability that at least one of the two hazards occurs in a given year is \(0.70\), and the two hazards are assumed to occur independently. Determine the annual probability (to three decimal places) that a flood occurs in the district.
