What is Binomial Distribution?

A Binomial Distribution is a probability distribution that describes the number of successful outcomes in a fixed number of independent trials. Each trial has only two possible outcomes, typically labeled "success" and "failure".
The Binomial Distribution is defined by two parameters: the probability of success (p) in a single trial, and the number of trials (n).
The probability of getting exactly k successful outcomes in n trials is given by the binomial probability formula. P(x) = (n choose x) * (p^x) * ((1-p)^(n-x))

It is also a discrete probability distribution, and is used to model the number of successes in a fixed number of Bernoulli trials with a fixed probability of success.
