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.
Binomial distribution probability marbles.
Success yes true one with probability p or failure no false zero with probability q 1 p.
I e it is an exchangeable distribution.
What is a binomial probability.
We have only 2 possible incomes.
The binomial distribution describes the probability of having exactly x successes in n independent trials with probability of a success.
In simple words a binomial distribution is the probability of a success or failure results in an experiment that is repeated a few or many times.
Because the probability of success p is not the same for each trial we cannot use the binomial formula.
As a result the probability of drawing a green marble in the draw is.
The prefix bi means two.
Find the probability you get exactly 3 blue marbles.
The probability of drawing any set of green and red marbles the hypergeometric distribution depends only on the numbers of green and red marbles not on the order in which they appear.
Binomial probability distributions are very useful in a wide range of problems experiments and surveys.
