The video tutorial covers fundamental probability concepts, including the range of probabilities, the sum of probabilities for all possible outcomes, and calculating probabilities for specific events. It distinguishes between disjoint and independent events and explains how to calculate probabilities for multiple independent events. The tutorial also addresses complex probability problems, emphasizing efficient calculation methods.
