Exploring Experimental Probability Through Real-Life Experiments

The video tutorial explains how to calculate both theoretical and experimental probabilities using a spinner. Theoretical probability is determined by the ratio of favorable outcomes to total outcomes without conducting an experiment. Experimental probability is found by performing an experiment and recording the results. The video demonstrates an experiment with a spinner, recording the outcomes, and calculating the experimental probability of spinning a specific number.
