Theoretical and Experimental Probability

This video tutorial covers the concepts of theoretical and experimental probability. It explains how to calculate probabilities as ratios, fractions, decimals, and percentages. Theoretical probability is discussed as the expected probability based on equally likely outcomes, while experimental probability is determined through actual experiments or simulations. The video provides examples, such as rolling a number cube, to illustrate the differences between theoretical and experimental probabilities.
