A binomial distribution is a probability distribution that describes the number of successes in a given number of independent trials.
The conditions needed for a binomial distribution are:
- n independent trials
- the probability of success for each trial is a constant, p
- only 2 outcomes (success and failure)
Important Concepts for Binomial Distribution
- If X takes binomial distribution, we write it as X~B(n,p)
- Our graphic calculator (Ti-84) is designed to find P(X=x) and P(X≤x)
- To find P(X=x), use binompdf
- The formula booklet also provides information on how to find P(X=x) manually.
- To find P(X≤x), use binomcdf
