Poisson distribution

This applet represents some features about the Poisson distribution, very useful to describe the probability of events wich occur with a known average rate and independtly of the occurrence of the last event, like nuclear decay processes or even car crashes.

Binomial distribution

The binomial distribution describes the probability of obtaining some number of successes in a sequence of n independent yes/no experiments. For example, the probability of obtaining exactly 3 heads in 5 rounds of coin tossing is P(5;3,0.5), being 0.5 the probability of success in a single round.
