What is Experimental Probability?

Back

Experimental Probability is the probability determined by performing an experiment and observing the outcomes. It is calculated as the ratio of the number of times an event occurs to the total number of trials.

Front

What is Theoretical Probability?

Back

Theoretical Probability is the ratio of favorable outcomes to the total number of possible outcomes in a given situation.

How do you calculate Experimental Probability?

Back

Experimental Probability = \frac{Number\ of\ favorable\ outcomes}{Total\ number\ of\ trials}.

Front

What is the difference between Experimental and Theoretical Probability?

Back

Experimental Probability is based on actual experiments, while Theoretical Probability is based on expected outcomes.

Front

What does it mean if an event has a probability of 1?

Back

It means the event is certain to occur.

What does it mean if an event has a probability of 0?

Back

It means the event is impossible and will not occur.

If a coin is flipped 100 times and lands on heads 55 times, what is the experimental probability of landing on heads?

Back

Experimental Probability of heads = \frac{55}{100} = 0.55.

What is a favorable outcome?

Back

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

Front

What is a sample space?

Back

A sample space is the set of all possible outcomes of a probability experiment.

Front

What is a trial in probability?

Back

A trial is a single performance of an experiment or observation.
