Random Variables
A random variable is a numerical outcome of a random process. It assigns a number to each possible event in a situation where the outcome is uncertain, like rolling a die or flipping a coin. There are two types: discrete random variables, which take specific values (like the outcome of a die roll), and continuous random variables, which can take any value within a range (like the height of people). Random variables help us quantify uncertainty and analyze data in statistics, allowing us to make predictions about future events based on past information.

A random variable is a number that represents the outcome of a random phenomenon. For example, when you roll a die, the number that shows up—like 1, 2, or 3—can be thought of as a random variable. It can take different values depending on chance, and we can study its behavior, like what values are more likely. Random variables help us quantify uncertainty and analyze situations in fields like statistics, finance, and science, allowing us to make predictions and informed decisions based on their possible outcomes.

A random variable is a numerical outcome associated with a random process or experiment. For example, if you roll a die, the number that appears is a random variable because it can vary with each roll, taking any value from 1 to 6. Random variables can be classified as discrete (specific outcomes, like rolling a die) or continuous (any value within a range, like measuring height). They're used in statistics and probability to analyze uncertainty and make informed decisions based on possible outcomes. Essentially, they help us quantify and understand randomness in different situations.
