h e cumulative distribution function is
where
h e binomial distribution has two parameters
N
and
p
. An example for the
application of this distribution is to determine the likely outcome of drilling
for oil. Let us assume that the probability of drilling success is 0.1 or 10%.
h e probability of
x
=3 successful wells out of a total number of
N
=10 wells is
h e probability of exactly 3 successful wells out of 10 trials is therefore 6%
in this example.
