Neco Model Questions Vol1 2018 Geography Question 10

The table below gives the annual probability (as a percentage), estimated damage cost (in million Naira) and vulnerability factor (scale 1-5) for three environmental hazards in a region.\n\n| Hazard | Probability (%) | Damage (million N) | Vulnerability |\n|----------|----------------|--------------------|---------------|\n| Flood | 4 | 120 | 4 |\n| Drought | 6 | 80 | 3 |\n| Landslide| 2 | 150 | 5 |\n\nThe risk index for a hazard is calculated as\n\( \text{Risk Index}= (\text{Probability}/100) \times \text{Damage} \times \text{Vulnerability}. \)\n\nCompute the risk index for each hazard and indicate which hazard should be given top priority for mitigation. Provide the name of the hazard.
