Bernoulli Trial

A test in which there are precisely two random outcomes: success and failure. For example, if one is testing whether flipping a coin will result in heads, the two outcomes are yes (success) and no (failure). See also: Bernoulli's Law.

Consider an infinite sequence of Bernoulli trials with probability of success p in every trial.
Just as before, consider an infinite sequence of Bernoulli trials with probability of success p in every trial.
A Geometric random variable represents the number of failures occurred before the first success, in an infinite sequence of Bernoulli trials. Therefore, we simulate Bernoulli trials and count the number of failures before the occurrence of the first success.
The outcome of each of the T x R Bernoulli trials (all of which have success probability p) was simulated using NAG subroutine G05DZF (Numerical Algorithms Group, 1999), and 20,000 such tables were generated per simulation condition.
The probability density function that comes from Bernoulli trials is the binomial pdf, which gives the probability, p, of r successes in n trials of an experiment.
It is fairly easy to derive the mean and variance of the binomial distribution because we can depict Bernoulli trials in several ways.
Actually, a Poisson distribution is not described by events with two possible outcomes and a constant probability of success as are Bernoulli trials. However, under certain conditions, we can use the Poisson distribution to solve Bernoulli problems.

Blocks Account for some systematic source of variability within the data and remove it from the experimental error by placing it within the blocks, such as selecting fields as blocks in a variety trial experiment because they have different soil types.
