Probability theory is a branch of mathematics that deals with the study of uncertainty and randomness. It provides a framework for quantifying the likelihood of events occurring.
Think of probability theory as a weather forecast. Just like meteorologists use data to predict the chances of rain, probability theory helps us calculate the chances of different outcomes happening.
Random Variable: A random variable is a numerical value that represents an uncertain outcome in probability theory.
Conditional Probability: Conditional probability measures the likelihood of an event occurring given that another event has already occurred.
Law of Large Numbers: The law of large numbers states that as more observations are made, the average outcome will converge to its expected value.
