Experimental Probability Flashcard

Front

What is experimental probability?

Back

Experimental probability is the probability determined by performing an experiment and calculating the ratio of the number of times an event occurs to the total number of trials.

How do you calculate experimental probability?

Back

Experimental probability is calculated using the formula: P(E) = Number of successful outcomes / Total number of trials.

What is the difference between theoretical probability and experimental probability?

Back

Theoretical probability is based on expected outcomes in a perfect world, while experimental probability is based on actual results from experiments.
