Binomial Distribution      • Only two outcomes are possible on
each of n trials.    • The probability of success for each trial
is constant.    • All trials are independent of each other.
The binomial distribution uses the following parameters.
NNumber of trialspositive integer pProbability of success
Probability Density Function  The probability density function
(pdf) is  where x is the number of successes in n trials of a
Bernoulli process with probability of success p.  Descriptive
Statistics  The mean is  The variance is  Relationship to Other
Distributions  The binomial distribution is a generalization of
the Bernoulli distribution, allowing for a number of trials n
greater than 1. The binomial distribution generalizes to the
multinomial distribution when there are more than two possible
outcomes for each trial.   Suppose you are collecting data from
a widget manufacturing process, and you record the number of
widgets within specification
