Insurers must estimate the average frequency and severity of future losses to set premium rates

• A. Statistically predictable
• B. Not catastrophic
• C. Definite and measurable
• D. Due to chance

Answer: (A)

The main idea is that pricing insurance relies on using data to forecast what will happen on average. Actuaries combine how often losses occur (frequency) with how large those losses are (severity) across a large group of similar exposures. Because this is based on statistics from many policies, the insurer can predict the average losses, making premium rates statistically predictable rather than exact for each individual policy. The law of large numbers helps actual results cluster around these expected values as the pool grows, though individual outcomes still vary. Catastrophic events and other uncertainties are handled separately, so the prediction isn’t guaranteed or definite, but it is grounded in probabilistic estimates.
