Solution Steps

The question is not a math problem that requires a computational solution, but rather a conceptual question about probability terminology. Therefore, it does not require a Python code solution.### Step 1: Understand the Question

The question asks us to select the appropriate term that describes a numerical outcome of a probability experiment. We are given four options to choose from.

Step 2: Analyze the Options

  1. Expected Value: This is the average or mean value expected in a probability distribution over many trials. It is not a single outcome but rather a measure of central tendency.

  2. Probability Distribution: This is a function that describes the likelihood of different outcomes in a probability experiment. It is not a single outcome but a collection of probabilities for all possible outcomes.

  3. Sample: This refers to a subset of a population used to represent the entire group. It is not specifically related to a single numerical outcome of a probability experiment.

  4. Random Variable: This is a variable that takes on numerical values determined by the outcome of a probability experiment. It represents the numerical outcome of the experiment.

Step 3: Select the Correct Option

Based on the analysis, the term that best describes a numerical outcome of a probability experiment is a "random variable."

Final Answer

The answer is \(\boxed{\text{a random variable}}\).
