Which term is the ratio expressing the likelihood that an event would occur if given 100 opportunities?

• A. Percentage
• B. Latency
• C. Percent duration
• D. Percent correct

Answer: (A)

Expressing how often something happens when you have a fixed number of chances uses percent. A percentage is a ratio with a base of 100, so when there are 100 opportunities, the number of times the event occurs directly translates to the percentage. For example, if the event happens 40 times in 100 opportunities, that’s 40 percent likelihood. Latency refers to time elapsed before a response, not how often something occurs. Percent duration describes the portion of total time that something lasts, which is about time, not frequency. Percent correct is the proportion of correct responses, a specific kind of accuracy, but the question asks for a general likelihood across 100 opportunities, which is best captured by percent.
