What is the difference between when to use a binomial distribution vs a geometric distribution.

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.
