Binomial distribution - Wikipedia
In probability theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a sequence of n independent experiments, each asking a yes–no question, and each with its own Boolean -valued outcome: success (with probability p) or failure (with probability q = 1 − p).

8.4: Binomial Distribution - Mathematics LibreTexts
2024年11月11日 · The outcomes of a binomial experiment fit a binomial probability distribution. The random variable \(X =\) the number of successes obtained in the \(n\) independent trials. The mean of \(X\) can be calculated using the formula \(\mu = np\), and the standard deviation is given by the formula \(\sigma = \sqrt{npq}\).
Binomial Distribution - Definition, Formula & Examples | Probability
In probability theory and statistics, the binomial distribution is the discrete probability distribution that gives only two possible results in an experiment, either Success or Failure.
Binomial Distribution in Probability | Formula, Definition
2024年12月4日 · Binomial Distribution is a probability distribution used to model the number of successes in a fixed number of independent trials, where each trial has only two possible outcomes: success or failure.
The Binomial Distribution - Math is Fun
The General Binomial Probability Formula: P(k out of n) = n!k!(n-k)! p k (1-p) (n-k) Mean value of X: μ = np; Variance of X: σ 2 = np(1-p) Standard Deviation of X: σ = √(np(1-p))
Binomial Distribution: Formula, What it is, How to use it
The binomial distribution evaluates the probability for an outcome to either succeed or fail. These are called mutually exclusive outcomes, which means you either have one or the other — but not both at the same time.
Binomial Distribution Formula: Probability, Standard Deviation
In this post, I’ll walk you through the formulas for how to find the probability, mean, and standard deviation of the binomial distribution and provide worked examples. Note that this post focuses on the binomial distribution formulas and calculations.
Binomial distribution | Properties, proofs, exercises - Statlect
The distribution of the number of experiments in which the outcome turns out to be a success is called binomial distribution. The distribution has two parameters: the number of repetitions of the experiment and the probability of success of an individual experiment.
