## What are the required assumptions for a binomial experiment?

## What makes a binomial a binomial?

The binomial is **a type of distribution that has two possible outcomes** (the prefix “bi” means two, or twice). For example, a coin toss has only two possible outcomes: heads or tails and taking a test could have two possible outcomes: pass or fail. A Binomial Distribution shows either (S)uccess or (F)ailure.

## What makes a binomial experiment?

A binomial experiment is **an experiment where you have a fixed number of independent trials with only have two outcomes**. For example, the outcome might involve a yes or no answer.

## What are the 4 characteristics of a binomial experiment?

1: The number of observations n is fixed. 2: Each observation is independent. 3: Each observation represents one of two outcomes ("success" or "failure"). 4**: The probability of "success" p is the same for each outcome.**

## How do you know if a question is binomial?

A random variable is binomial if the following four conditions are met: **There are a fixed number of trials (n)**. ... The probability of success (call it p) is the same for each trial. The trials are independent, meaning the outcome of one trial doesn't influence the outcome of any other trial.Mar 26, 2016

Overview. The geometric distribution is a one-parameter family of curves that **models the number of failures before one success in a series of independent trials**, where each trial results in either success or failure, and the probability of success in any individual trial is constant.

### What is a binomial experiment example?

**Binomial**experiments are random experiments that consist of a fixed number of repeated trials, like tossing a coin 10 times, randomly choosing 10 people, rolling a die 5 times, etc. These trials, however, need to be independent in the sense that the outcome in one trial has no effect on the outcome in other trials.

Remember,**binomial**is for independent events where the likelihood of each event occurring is the same as the others.
