Probability and Theoretical Probability Quiz

This video tutorial introduces the concept of probability, explaining its definition and how it can be represented on a continuum from impossible to certain. It covers key vocabulary such as outcomes and theoretical probability, providing examples like coin tosses and dice rolls. The tutorial also explains how to calculate probability using fractions, decimals, and percentages, and discusses complementary events, emphasizing the sum of probabilities equaling one. Students are encouraged to apply these concepts through examples and exercises.
