List of Probability Topics

Probability theory is a branch of mathematics concerned with analyzing random phenomena. The fundamental objects of probability theory are random variables, stochastic processes, and events: mathematical abstractions of non-deterministic events or measured quantities that may either be single occurrences or evolve over time in an apparently random fashion. This article aims to provide a comprehensive list of topics related to probability theory, each of which plays a crucial role in understanding the behavior of systems affected by randomness.

Basic Concepts[edit | edit source]

  • Probability Space: The mathematical construct that models a random experiment. It consists of a sample space, a set of events, and a probability measure.
  • Random Variable: A variable whose possible values are numerical outcomes of a random phenomenon.
  • Probability Distribution: Describes how probabilities are distributed over the values of the random variable.
  • Expected Value: The weighted average of all possible values that a random variable can take on.
  • Variance and Standard Deviation: Measures of how spread out the values of a random variable are.
  • Law of Large Numbers: A theorem that describes the result of performing the same experiment a large number of times.
  • Central Limit Theorem: States that, under certain conditions, the sum of a large number of random variables will be approximately normally distributed.

Probability Distributions[edit | edit source]

  • Binomial Distribution: The probability distribution of the number of successes in a sequence of independent experiments.
  • Poisson Distribution: A discrete frequency distribution that expresses the probability of a given number of events occurring in a fixed interval of time or space.
  • Normal Distribution (Gaussian distribution): A very common continuous probability distribution - symmetric and bell-shaped.
  • Exponential Distribution: The probability distribution that describes the time between events in a Poisson point process.
  • Gamma Distribution: A two-parameter family of continuous probability distributions.

Stochastic Processes[edit | edit source]

  • Markov Chains: Models of random processes that undergo transitions from one state to another on a state space.
  • Brownian Motion: A continuous-time stochastic process used to model random movement.
  • Poisson Process: A stochastic process that models a series of events occurring at random points in time.
  • Random Walk: A mathematical formalization of a path that consists of a succession of random steps.

Advanced Topics[edit | edit source]

Applications[edit | edit source]

Probability theory is applied in a wide variety of fields, including Statistics, Finance, Gambling, Science, Engineering, and Information Technology.
