The binomial test is used for the study of rare events. It calculates the exact probability of finding 'x' or more failures (or white or male or large or tail) as opposed to n-x or less successes (or black or female or small or heads) after having done 'n' experiments, 'n' observations or studying a sample of size 'n'. This particular procedure also gives a double sided binomial probability.
