which data values, or ranges of data values, occur and
are represented by histograms or frequency charts.
• They are normally based on historic data.
• Most simulation software enable the user directly to

• The binomial distribution describes the number of
successes, or failures, in a specified number of trials.
• It can be used, for instance, to model the number of
defects in a batch of items.
• The distribution has two parameters, the number of
trials and the probability of success.
