Distribution Calculator
The Binomial Distribution
gives the discrete probability
distribution Pp(n|N)
of obtaining exactly n successes
out
of N Bernoulli trials (where the
result of each Bernoulli trial is true with probability p
and false with probability q
= 1-p). The binomial distribution is
given by
The binomial distribution
calculator below asks to enter
three parameters: the number of trials (N),
the exact number of successes (n), and the probability of success (p).
Example:
What is
the probability that in five rolls of a fair die, a one appears twice?
N
= 5
n = 2
p = 1/6 = 0.16666
Answer = 0.16075
