7. Probability Distribution Function (PDF)

Probability Distribution Functions (PDFs) provide a mathematical framework for handling uncertainty and randomness in engineering and applied sciences. Key topics include the definitions and properties of PDFs, the relationship between PDFs and cumulative distribution functions (CDFs), common probability distributions, and their applications in various engineering fields. Additionally, PDFs are crucial for solving Partial Differential Equations like the Fokker-Planck equation, linking randomness to time-evolving systems.
