The binomial distribution helps in finding the probability that a number k of successful event is happening in a given series of attempts, while the geometric distribution helps in finding the first failure when performing a number of attempts.

The common thing that binomial and geometric distributions have in common is that they are based on independent series of attempts. A special case of negative binomial distribution oR Pascal distribution is represented by the geometric distribution.
