Probability Distribution
Probability distribution is a fundamental concept in statistics and probability theory, serving as a mathematical framework for understanding the likelihood of various outcomes in a random experiment or process. It provides a systematic way to describe the possible values and their associated probabilities, enabling analysts to make informed decisions and predictions based on data. Understanding different probability distributions is essential for modeling real-world phenomena, conducting statistical inference, and solving a wide range of practical problems across various fields, from finance and engineering to biology and social sciences.
