The video tutorial discusses calculating probabilities when there is only one trial. It begins with an introduction to the concept of a trial in a random procedure. The tutorial then explains how to calculate the probability of rolling a specific number on a six-sided die, emphasizing the concept of disjoint events. It further explores the probability of rolling a five or a six and introduces a formula for disjoint events. The tutorial concludes with a practical example using playing cards to demonstrate how to calculate probabilities when events are not disjoint.
