What is Theoretical Probability?

Back

Theoretical Probability is the likelihood of an event happening based on all possible outcomes. It is what should happen in an ideal situation.

What does it mean when we say 'experimental probability'?

Back

Experimental Probability is the likelihood of an event happening based on actual experiments or trials.

Front

How do you calculate Experimental Probability?

Back

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

What is the difference between theoretical and experimental probability?

Back

Theoretical probability is based on expected outcomes, while experimental probability is based on actual results from experiments.
