Binomial Distribution Probability Marbles

In binomial probability distribution the number of success in a sequence of n experiments where each time a question is asked for yes no then the boolean valued outcome is represented either with success yes true one probability p or failure no false zero probability q 1 p.

Binomial distribution probability marbles.

The above is a randomly generated binomial distribution from 10 000 simulated binomial experiments each with 10 bernoulli trials with probability of observing an event of 0 2 20. 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. 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 yes true one with probability p or failure no false zero with probability q 1 p.

Binomial probability distributions are very useful in a wide range of problems experiments and surveys. The prefix bi means two. As a result the probability of drawing a green marble in the draw is. Because the probability of success p is not the same for each trial we cannot use the binomial formula.

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. I e it is an exchangeable distribution. The binomial distribution describes the probability of having exactly x successes in n independent trials with probability of a success. We have only 2 possible incomes.
