The Erlang distribution is a fundamental continuous probability distribution that originated in the field of stochastic processes. It was originally developed by the Danish mathematician Agner Krarup Erlang in the early 20th century to solve crucial problems related to congestion in telephone systems. This distribution is often described as the probability distribution of the sum […]
In the study of probability distributions, a fascinating and critically important concept is the memoryless property. This unique characteristic defines a system where the probability of a future event occurring is completely independent of its past history or the amount of time that has already elapsed. In essence, any probabilistic system or process possessing this

The Exponential Distribution is an essential probability distribution used widely across statistical modeling, financial analysis, and reliability engineering. It is uniquely suited to model the time elapsed until a specific event occurs, assuming these events happen continuously and independently at a constant average rate. This powerful characteristic makes it the cornerstone for analyzing waiting times,

In the expansive field of statistics, the gamma distribution stands out as an exceptionally versatile continuous probability distribution. It is routinely employed to accurately model positive, right-skewed data across numerous disciplines, offering a robust framework for phenomena such as waiting times in queueing systems, cumulative damage in reliability engineering, or predicting rainfall totals and insurance
The Gamma distribution stands as one of the most fundamental and versatile continuous probability distributions utilized in statistics and applied mathematics. Its utility lies primarily in its ability to model continuous, positive random variables—phenomena that cannot take negative values. This makes it indispensable across diverse fields, from actuarial science, where it models the severity of
