Adding and Subtracting Rational Expressions

This lesson covers theoretical and experimental probability, explaining the concepts and providing examples. It begins with an introduction to probability, followed by practical examples using a spinner to calculate probabilities of various outcomes. The lesson then explores probability problems involving markers, playing cards, and true or false quiz questions. It also discusses the complement of an event and concludes with a comparison between theoretical and experimental probability using a spinner.

How does experimental probability differ from theoretical probability?

• It's based on actual results from experiments.

• It's always a fraction.

• It can only be determined with a calculator.

• It's always higher than theoretical probability.
