Binomial Distribution

The binomial distribution describes the number of successes ($k$) in a fixed number of independent trials ($n$), each with a success probability $p$.

$$ P(X=k) = \binom{n}{k} p^k (1-p)^{n-k} $$

Poisson Distribution

The Poisson distribution expresses the probability of a number of events ($k$) occurring in a fixed interval, given an average rate $\lambda$.

$$ P(X=k) = \frac{\lambda^k e^{-\lambda}}{k!} $$
