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 =).
Learn what is binomial distribution, a discrete probability distribution that gives only two possible results in an experiment. Find the formula, mean, variance, properties and examples of binomial distribution and its relation with normal distribution.
- The binomial distribution is the discrete probability distribution that gives only two possible results in an experiment, either success or failure.
- The formula for binomial distribution is: P(x: n,p) = n C x p x (q) n-x Where p is the probability of success, q is the probability of failure...
- The mean and variance of the binomial distribution are: Mean = np Variance = npq
- The number of trials should be fixed. Each trial should be independent. The probability of success is exactly the same from one trial to the othe...

The binomial distribution is a discrete probability distribution that calculates the likelihood an event will occur a specific number of times in a set number of opportunities. Use this distribution when you have a binomial random variable. These variables count how often an event occurs within a fixed number of trials. They have only two possible ...
The binomial distribution models the probabilities for exactly X events occurring in N trials when the probability of an event is known for a binomial random variable. Let’s get into some examples because that brings it to life! I’ll start by using statistical software to calculate the binomial probabilities and create distribution plots. This proc...
The binomial distribution graph is useful because it displays the probability of differing numbers of successes (Xs) out of the total number of trials (N). In the graph below, the distribution plot finds the likelihood of rolling exactly no sixes, 1 six, 2 sixes, 3 sixes, . . ., and up to 10 sixes in the ten die rolls. Using this approach, the bino...
The binomial probability distribution is excellent for understanding the likelihood of obtaining an exact number of events (X) within a certain number of trials (N). However, many times you’re not interested in just one specific value for a binomial random variable. For example, in the die rolling example above, you might know from experience that ...
The binomial distribution models the probabilities for a binomial random variable having exactly X successes occurring in N trials. Your variable must satisfy the following requirements to be a binomial random variable. The binomial distribution is appropriate only for data that fulfill these assumptions. 1. There must be only two possible outcomes...
Use this binomial distribution calculator to calculate the binomial probabilities and cumulative probabilities. Note that it uses “events” to indicate the number of trials (n). Let’s use this calculator to recreate the preceding die examples. In the calculator, enter Number of events (n) = 10, Probability of success per event (p) = 16.67%, choose e...
