Theoretical vs. Experimental Probability

Front

What is Theoretical Probability?

Back

Theoretical probability is the likelihood of an event happening based on all possible outcomes. It is calculated using the formula: P(Event) = Number of favorable outcomes / Total number of possible outcomes.

What is Experimental Probability?

Back

Experimental probability is the likelihood of an event happening based on actual experiments or trials. It is calculated using the formula: P(Event) = Number of times the event occurs / Total number of trials.

Front

What is the experimental probability of an event?

Back

It is determined by conducting an experiment and observing how often the event occurs.
