Final answer:
The expected loss in risk assessment is calculated by multiplying the impact of an event by its likelihood.
Step-by-step explanation:
The expected loss is calculated in risk assessment by multiplying the impact of an event by its likelihood.
This can be represented by the formula:
Expected Loss = Impact x Likelihood
For example, if an event has a high impact and a high likelihood of occurring, the expected loss will be greater compared to an event with low impact and low likelihood.
