Practice objective / multiple choice question 48 from the 2025 Neco Model Questions Vol1 Geography examination.
A community located beside a river experiences flooding. Historical records show a flood occurs once every 12 years. If a flood occurs, the average economic loss is \(\₦4.5\) million. The community can adopt one of two mitigation measures:\n\n*Measure A*: reduces the probability of flooding by \(30\%\) (the reduction is multiplicative) and costs \(\₦500{,}000\) per year.\n\n*Measure B*: reduces the average economic loss per flood by \(25\%\) and costs \(\₦800{,}000\) per year.\n\nAssuming the probability and loss figures apply to a single year, which single measure results in the lower total expected annual loss (including the annual cost of the measure)?
