Probability and Basic Math Concepts

The video tutorial covers theoretical probability, contrasting it with experimental probability. It provides examples using marbles, dice, and a spinner to illustrate how to calculate probabilities. The tutorial also includes a practical scenario at a school fair to determine the best choice for winning a prize. Finally, it offers an independent practice exercise to reinforce the concepts learned.

What is the main difference between experimental and theoretical probability?

• Experimental probability is based on actual experiments, while theoretical is based on predictions.

• Theoretical probability is always more accurate than experimental probability.

• Experimental probability uses predictions, while theoretical uses actual data.

• There is no difference between experimental and theoretical probability.
