geometric distribution

The geometric distribution is a probability distribution that models the number of failures before the first success in a series of independent Bernoulli trials. It is particularly useful in scenarios where you are interested in the waiting time until a specific event occurs. For example, it can be applied in various fields such as finance, sports, and commerce to analyze the likelihood of achieving a success after a certain number of failures 12.

In mathematical terms, the geometric distribution is defined by a single parameter ( p ), which represents the probability of success on each trial. The probability mass function (PMF) gives the probability of observing ( y ) failures before the first success, expressed as ( P(Y = y) = (1-p)^y \cdot p ). The expected value and variance of the distribution can also be derived from this parameter, providing insights into the average number of trials needed to achieve the first success 24.

If you have any specific questions or need further clarification on the geometric distribution, feel free to ask!
