The ratio of the number of desired outcomes that occurred during the experiment to the total number of trials performed in the experiment.

• Percentage

• Experimental Probability

• Ratio of Outcomes

• Theoretical Probability

The ratio of the number of desired outcomes for an event to the total number of possible outcomes

• Experimental Probability

• Theoretical Probability

• Probability

• Ratio

What is the difference between experimental probability and theoretical probability.

• Experimental is done in a lab.

• You have to think about theoretical probability.

• Theoretical probability is never correct and experimental is sometimes correct.

• One is mathematically calculated before an event. The other is calculated after an experiment or event happened.
