Experimental vs Theoretical Probability

Front

What is Experimental Probability?

Back

Experimental Probability is what actually happens based on the results of an experiment.

Front

What is Theoretical Probability?

Back

Theoretical Probability is what should happen based on the possible outcomes.

Front

If a spinner has 4 equal sections, what is the theoretical probability of landing on any one section?

Back

1/4 or 25%.

Front

What is the formula for calculating Experimental Probability?

Back

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

Front

If you flip a coin 100 times, how many times would you expect to land on heads?

Back

Approximately 50 times.

Front

What is the theoretical probability of not landing on red if there are 3 red and 6 other colors in a spinner?

Back

66.7%.

Front

What does it mean if an experiment has a high experimental probability?

Back

It means that the event occurred frequently in the trials conducted.

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

If a bag contains 10 jelly beans (3 red, 7 blue), what is the theoretical probability of picking a red jelly bean?

Back

30% or 3/10.

Front

What is the expected number of times a 4 would be rolled if a die is rolled 60 times?

Back

10 times (1/6 of 60).
