Try, try and try again till you succeed. That is Geometric distribution.

*If we consider independent Bernoulli trials of 0s and 1s with some probability of occurrence p and assume X to be a random variable that measures the number of trials it takes to see the first success, then, X is said to be Geometrically distributed.*

In lesson 33, we learn the basics of Geometric distribution.
