The video tutorial introduces probability distributions, focusing on random variables, both discrete and continuous. It explains how discrete random variables map outcomes to numerical values, using examples like coin flips. Continuous random variables, such as measuring height, are also discussed. The tutorial covers discrete probability distributions, including their representation in tables, graphs, and functions. Key properties of these distributions are highlighted, and an example problem is solved to find a missing probability value.
