**probability density**

The term **probability density** refers to a function that describes the relative likelihood of a continuous random variable to take on a specific value. In probability theory and statistics, the probability density function (PDF) is used to specify the probability that the variable falls within a particular range of values, rather than taking any exact value. The area under the curve of the PDF over an interval represents the probability of the variable residing within that interval. Probability density is fundamental in fields such as data analysis, machine learning, and statistical modeling.
