Comparing Probabilities: Union and Intersection of Events

The video tutorial explains the probability concepts of union and intersection using a lucky envelope game. It begins with an introduction to the problem, followed by a detailed explanation of intersection and union using Venn diagrams. The tutorial then calculates the probabilities of selecting red and lucky envelopes, and compares the probabilities of union and intersection. The lesson concludes by reinforcing the understanding of these concepts through a two-way table.
