Random Variables and Probability Distribution Quiz

Random Variables and Probability Distributions

• A random variable represents a numerical outcome or value that results from a random experiment or process.
• A random variable can be either discrete (taking on specific distinct values) or continuous (taking on any value within a certain range or interval).

Probability Distribution

• A probability distribution describes the probability of each possible value or outcome of a random variable.
• It provides a summary of the probability of each possible outcome, and can be used to calculate the likelihood of different events or outcomes.

Mean of a Probability Distribution

• The mean of a probability distribution is a measure of the central tendency or expected value of the random variable.
• It represents the long-run average value of the random variable, and is often denoted by the symbol μ (mu).
