The measure of the likelihood of a given event occurring.
The correct answer is D. Probability. Probability (D) is defined as the measure of the likelihood that a specific event will occur, expressed as a value between 0 (impossible) and 1 (certain) - this is its textbook definition, making D the direct match.

Explanation
Probability (D) is defined as the measure of the likelihood that a specific event will occur, expressed as a value between 0 (impossible) and 1 (certain) - this is its textbook definition, making D the direct match.
Why the distractors are wrong:
- A. Risk refers to the potential for loss or harm from an uncertain event, not the mathematical measure of its likelihood.
- B. Hypothesis Test is a statistical method used to determine whether evidence supports or rejects a claim - it uses probability but is not its definition.
- C. Cause and Effect Diagram (Fishbone/Ishikawa) is a quality tool for identifying root causes of a problem - unrelated to measuring likelihood.
Memory tip: Think of the word probable - if something is probable, it is likely to happen. Probability = probable = likelihood. The other options are tools or concepts that apply probability, but only D is probability.
