Understanding the normal distribution with the clearest explanation

Artificial Intelligence | AI on Instagram: "A probability density function (PDF) describes the probability of a random variable taking some specific value, with the area under the curve (AUC, which can be calculated using an integral) representing the probability of the variable falling within a specific range. The expectation (expected value) is the mean of a random variable, representing the average value of a distribution. A Joint distribution captures the probability of two or more random va
