What is Experimental Probability?

Back

Experimental Probability is the probability of an event occurring based on the results of an experiment or trial, calculated as the number of times the event occurs divided by the total number of trials.

Front

How do you calculate Experimental Probability?

Back

Experimental Probability = (Number of times the event occurs) / (Total number of trials)

Front

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 trials.

Front

What is a trial in the context of probability?

Back

A trial is a single occurrence or observation in an experiment, such as rolling a die or flipping a coin.

Front

What does it mean if an experimental probability is close to 1?

Back

It means that the event is likely to occur based on the results of the experiment.
