Theoretical and Experimental Probability

In this math video lesson we will learn about theoretical and experimental probability. We will define theoretical probability as the ratio of the number of favorable outcomes to the number of possible outcomes. We will review possible outcomes using a spinner as a model. We will define experimental probability the probability of an event happening when an experiment is performed. It is represented as the ratio of the number of times the event occurred to the number of trials conducted. We will review the data collected from spinning a spinner using a simulator and review the data collected. We will understand that the more trials conducted, the closer the experimental probability will be to the theoretical probability. We will learn about relative frequency. Relative frequency is the number of times you would expect an outcome to occur during an experiment. We will find relative frequency. Student practice is provided in the lesson and exemplar solutions are modeled and explained.
