Experimental Probability

Front

What is experimental probability?

Back

Experimental probability is the probability determined by conducting an experiment and observing the outcomes. It is calculated as the number of times an 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 formula for calculating the experimental probability of landing on a specific number when spinning a spinner?

Back

Experimental probability = (Number of times the specific number is landed on) / (Total spins)

Front

If a spinner is spun 200 times and lands on '3' 50 times, what is the experimental probability of landing on '3'?

Back

Experimental probability = 50/200 = 0.25 or 25%.

Front

What is theoretical probability?

Back

Theoretical probability is the probability of an event occurring based on the possible outcomes in a perfect scenario, without conducting any experiments.

Front

How is theoretical probability calculated?

Back

Theoretical probability = (Number of favorable outcomes) / (Total number of possible outcomes)

Front

If a die is rolled, what is the theoretical probability of rolling a 6?

Back

Theoretical probability = 1/6, since there is one favorable outcome (rolling a 6) out of six possible outcomes.

Front

What is the difference between experimental and theoretical probability?

Back

Experimental probability is based on actual experiments and observed outcomes, while theoretical probability is based on expected outcomes in a perfect scenario.

Front

If Kate spun a spinner 75 times and landed on '3' 30 times, what is the experimental probability of landing on '3' as a percentage?

Back

Experimental probability = (30/75) * 100 = 40%.

Front

What does it mean to perform an experiment in probability?

Back

Performing an experiment in probability means conducting trials to observe outcomes and gather data to calculate experimental probability.
