Experimental Probability Lesson

Experimental probability

Lesson objective: to calculate the experimental probability of events occuring

Experimental probability is what actually does happen after you have performed the experiment

Multiple Choice

What type of probability is a way of estimating the probability of an event happening based on repeated trials?

• Experimental Probabillity

• Theoretical Probability
