The sum of independent random variables is crucial in probability theory, enabling the analysis of multiple stochastic processes. The Convolution Theorem simplifies the calculation of their combined probability generating functions (PGFs), expectation, and variance. This theorem is vital for operations research, risk management, and quality control, and is applicable to various distributions, including binomial and uniform.
