Neco Model Questions Vol1 2023 Geography Question 2
Practice objective / multiple choice question 2 from the 2023 Neco Model Questions Vol1 Geography examination.
The annual probability of a flood in Region A is \(p_f\) and that of a landslide is \(p_l\). The average economic loss per flood is \(\text{₦}2.5\) million and per landslide is \(\text{₦}1.8\) million. The expected annual loss is \(\text{₦}1.5\) million and the ratio of the probabilities is \(p_f:p_l = 3:2\). A mitigation programme reduces the flood probability by \(20\%\) and the landslide probability by \(10\%\) (relative reductions). After implementation, what is the new expected annual loss (in million naira) and does it achieve at least a \(40\%\) reduction from the original expected loss? Answer with the new loss rounded to two decimal places and "Yes" or "No".
