The geometric distribution is used to model the number of trials needed until the first success occurs in a series of independent Bernoulli trials. In other words, it answers the question, “How many attempts do

we need to achieve a certain outcome?”

**For example,** imagine flipping a fair coin until you get heads. The geometric distribution can tell you the probability of getting heads on the first, second, third, or any specific trial. Each trial has two possible outcomes: success (getting heads) or failure (getting tails).
