Concept:Insurable risks must have statistical data that helps the insurer calculate the probability of loss.
Explanation:Insurance companies rely on past records and statistics to estimate the chance of a risk occurring.
These statistics allow them to work out fair premiums and decide whether the risk can be covered.
When no statistics are available, the risk cannot be measured or predicted accurately.
Without a reliable estimate, the insurer cannot set a premium or provide coverage.
Such risks fall outside the scope of insurance and are generally called uninsurable risks.
Therefore, the term used for risks lacking statistical calculation support is "uninsurable risks."
Answer:C. un-insurable risks
