Probability: theoretical and experimental

Front

What is the definition of experimental probability?

Back

Experimental probability is the ratio of the number of times an event occurs to the total number of trials conducted.

Front

What is the formula for calculating experimental probability?

Back

Experimental Probability = \frac{Number\ of\ favorable\ outcomes}{Total\ number\ of\ trials}.

Back

Theoretical probability is the ratio of the number of favorable outcomes to the total number of possible outcomes in a perfect scenario.
