Key Concepts

Poisson Distribution

A discrete probability distribution used to model the number of events occurring within a fixed interval of time or space, under the assumption that these events happen at a constant mean rate and are independent of each other.

Mean (?) Parameter

The parameter ? in the Poisson distribution represents the expected number of events in a given interval. It is a measure of the average event rate and is used in the probability mass function to compute the likelihood of observing a specific number of events.

Probability Mass Function (PMF)

The probability mass function for the Poisson distribution, given by P(X = k) = (e^(-?) * ?^k) / k!, is used to compute the probability of exactly k events occurring in the interval. This formula forms the basis for solving problems where the Poisson model is applicable.
