Canadian Forces Aptitude Test (CFAT) Practice

In a probability framework, if something is likely to occur, which probability range would it typically fall into?

1. 0 to 1/4

2. 1/2 to 3/4

3. 3/4 to 1

4. 0 to 1/2

The correct answer is: 3/4 to 1

In probability, events are quantified on a scale from 0 to 1, where 0 indicates impossibility and 1 indicates certainty. When we consider an event that is likely to occur, this typically suggests a high probability. The range from three-quarters (3/4) to one (1) represents events that are very likely to happen, indicating a strong expectation of occurrence. An event falling within this range would generally be perceived as having a high level of confidence that it will occur. This aligns with the common understanding of "likely," suggesting a strong probability rather than just a decent chance. The other ranges represent probabilities that are either uncertain or leaning towards a lesser likelihood, which does not align with the interpretation of something being likely to occur. Thus, the correct choice captures the essence of events that are expected to happen with a significant degree of assurance.
