Which of the following is an example of a natural frequency?

• A. 1 in 100
• B. 0.01 probability
• C. 2% risk
• D. 50 percent chance

Answer: (A)

Natural frequency expresses risk as a concrete count out of a fixed number of cases, which makes the likelihood easier to visualize. Saying “one in a hundred” communicates that out of a group of 100, about one would experience the event. That direct count is what defines a natural frequency.

So the example given as “one in a hundred” is the natural-frequency form. The other options describe likelihood as a probability or as a percentage (0.01 as a decimal probability, 2% risk, or 50% chance), which are not framed as a count out of a specified number of cases—even though they convey the same magnitude numerically, they don’t use the natural-frequency wording.
