Chapter 8 - The Binomial Probability Distribution Math 22 Introductory Statistics
Binomial Probability Experiment • Logic behind the Binomial distribution • Bernoulli Population - A population in which each element is one of two possibilities. The two possibilities are usually designated as success and failure. • Bernoulli Trial - Observing one element in a Bernoulli population.
Binomial Probability Experiment An experiment that consists of n repeated independent Bernoulli trials in which the probability of success on each trial is and probability of each failure is 1 - . is the prob. of success and will not be associated with 3.1415....
Binomial Probability Experiment • P(success)+P(failure) = 1 • The Binomial Probability Function is given by: • n represents the number of trials • k represents the number of successes • represents the prob. of success • 1- represents of prob. of failure
