Experimental Probability with a Spinner

The video tutorial explains an experiment with a spinner, detailing how it landed on different colors over 85 spins. It calculates the experimental probability of landing on red and uses this to estimate future outcomes over 500 spins. The importance of rounding results in exams is also discussed, with tips on how to ensure full marks.
