Key Concepts

Binomial Distribution

The binomial distribution is a discrete probability distribution that models the number of successes in a fixed number of independent experiments, each with the same probability of success. It is used when each trial has only two possible outcomes: success or failure.

Binomial Coefficient

The binomial coefficient represents the number of ways to choose a specific number of successes from a fixed number of independent trials. It is a key element in calculating probabilities in a binomial distribution and is calculated using factorials, embodying the concept of combinations.

Bernoulli Trial

A Bernoulli trial is a random experiment in which there are exactly two outcomes — typically labeled as success and failure. It is the building block for a sequence of independent trials that comprise the binomial experiment.

Probability Mass Function

The probability mass function (PMF) is a function that gives the probability that a discrete random variable is exactly equal to a particular value. In the context of the binomial distribution, it combines the binomial coefficient with the probabilities of success and failure raised to the appropriate powers.
