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.

How do you calculate Experimental Probability?

Back

Experimental Probability = (Number of favorable 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 trials.

Front

What is a favorable outcome in probability?

Back

A favorable outcome is an outcome that is considered successful for the event being measured.

Front

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

Back

If an experimental probability is close to 1, it means that the event is likely to occur based on the experimental results.
