Exploring Probability Word Problems

Mr. Buffington introduces probability, explaining its definition and how to calculate it. He provides examples using dice and spinners, then transitions to solving word problems involving marbles and book titles. The video also covers more complex problems, such as determining probabilities from a list of months and a pet shop scenario. The session concludes with a focus on identifying trick questions in probability, emphasizing careful reading and problem-solving strategies.
