This lesson covers how to calculate the moments (expectation and variance) of a random variable from its Probability Generating Function (PGF).
We explain the process of differentiating the PGF to find the first and second moments, with a clear, worked example to guide you through the steps.
Understanding moments is essential for analyzing and interpreting probability distributions in more depth.
