An experiment with only two outcomes ("success" and "failure"), a constant probability of success, a number of independent trials.
Then, if the probability of a success in a trial is p, the probability of r successes in n trials is
nCr*pr*(1-p)(n-r) for r = 0, 1, 2, ..., n.
In case the super-and sub-scripts do not work, that is
n!/[r!*(n-r)!]*p^r*(1-p)^(n-r)
what are the uses of binomial distribution
what is meant by a negative binomial distribution what is meant by a negative binomial distribution
You distribute the binomial.
The distribution depends on what the variable is. If the key outcome is the number on the top of the die, the distribution in multinomial (6-valued), not binomial. If the key outcome is the number of primes, composite or neither, the distribution is trinomial. If the key outcome is the number of sixes, the distribution is binomial with unequal probabilities of success and failure. If the key outcome is odd or even the distribution is binomial with equal probabilities for the two outcomes. Thus, depending on the outcome of interest the distribution may or may not be binomial and, even when it is binomial, it can have different parameters and therefore different shapes.
Use the continuity correction when using the normal distribution to approximate a binomial distribution to take into account the binomial is a discrete distribution and the normal distribution is continuous.

You distribute the binomial.
In a symmetric binomial distribution, the probabilities of success and failure are equal, resulting in a symmetric shape of the distribution. In a skewed binomial distribution, the probabilities of success and failure are not equal, leading to an asymmetric shape where the distribution is stretched towards one side.
Normal distribution is the continuous probability distribution defined by the probability density function. While the binomial distribution is discrete.
First i will explain the binomial expansion
It is necessary to use a continuity correction when using a normal distribution to approximate a binomial distribution because the normal distribution contains real observations, while the binomial distribution contains integer observations.
Binomial distribution is the basis for the binomial test of statistical significance. It is frequently used to model the number of successes in a sequence of yes or no experiments.
Poisson and Binomial both the distribution are used for defining discrete events.You can tell that Poisson distribution is a subset of Binomial distribution. Binomial is the most preliminary distribution to encounter probability and statistical problems. On the other hand when any event occurs with a fixed time interval and having a fixed average rate then it is Poisson distribution.

There is no such thing. The Normal (or Gaussian) and Binomial are two distributions.
