represented by the uncertainty on the likelihood

The practice of using the tag on risk is superficial and negligent (and thus in some contexts, even a risk).

This begins with the term "uncertainty" that the ISO 31000:2009 raises in their definition of risk.

Very fast, too soon is then probability (the occurrence of an event) as a percentage or frequency (of occurrence of an event) spoken in frequency, not just expected.

In computing with probabilities or frequencies, one in the metric system of numbers and uses the four basic operations and more. It has thus the demands for objectivity and transparency done enough. It operates on the paradigm of "if-then-else".

forgetting, or never asked the question whether the uncertainty of an event can be accurately described and evaluated with numbers and their metrics.

uncertainty is a psychological issue that has effects in the future.
probability and frequency are mathematical and statistical issues that are to describe and evaluate a model and a reality.

And another thing: probability and frequency are different models for uncertainty. They are not interchangeable or readily converted to one another. What is often made.
