Key Concepts

Binomial Distribution

The binomial distribution is a discrete probability distribution that describes the number of successes in a fixed number of independent trials, each with the same probability of success. It is widely used in situations where an experiment has two outcomes, such as success (heads) and failure (tails), allowing one to calculate the likelihood of obtaining a specific number of successes.

Bernoulli Trials

Bernoulli trials refer to experiments that have exactly two possible outcomes (commonly labeled as success and failure) and are characterized by a constant probability of success in each trial. When multiple Bernoulli trials are performed independently, the framework helps in analyzing events such as consecutive coin tosses.

Probability Multiplication Principle

The probability multiplication principle is used to determine the probability of multiple independent events occurring together. By multiplying the probabilities of each individual event, this principle allows one to compute the overall probability of compound events, such as getting a specific outcome in every trial.

Biased Coin

A biased coin, or unfair coin, is one where the outcomes do not have equal likelihoods. In probability theory, recognizing that the coin is biased is crucial because it directly affects the calculation of event probabilities, necessitating adjustments to standard formulas that assume equal chance.
