Poisson and Binomial Distributions Probability Calculator Applet

Probability calculator for discrete random distributions, mainly the Poisson and Binomial distributions.

Binomial Probability:

$$ \binom{n}{x} p^{x} \cdot (1-p)^{n-x}$$

Where:

n is the total number of bernouilli trials
x is the wanted number of successful bernouilli trials
p is the binomial probability of obtaining a success value in each bernouilli trial

Poisson Probability:

$$ \frac {e^{-\lambda} \cdot \lambda^x} {x!} $$

Where:

lambda is the characteristic poisson variable
x is the chosen variable in the random variable distribution
