Editing Binomial distribution (section)

== History ==

This distribution was derived by [[Jacob Bernoulli]]. He considered the case where {{math|1=''p'' = ''r''/(''r'' + ''s'')}} where {{math|''p''}} is the probability of success and {{math|''r''}} and {{math|''s''}} are positive integers. [[Blaise Pascal]] had earlier considered the case where {{math|1=''p'' = 1/2}}, tabulating the corresponding binomial coefficients in what is now recognized as [[Pascal's triangle]].<ref name=":1">{{cite book|last=Katz|first=Victor|title=A History of Mathematics: An Introduction|publisher=Addison-Wesley|year=2009|isbn=978-0-321-38700-4|pages=491|chapter=14.3: Elementary Probability}}</ref>
