Theoretical and Experimental Probability

Front

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 a perfect scenario.

Front

What is Experimental Probability?

Back

Experimental Probability is the likelihood of an event happening based on the results of an actual experiment.

Front

How do you calculate Theoretical Probability?

Back

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

If a spinner has 5 equal sections numbered 1 to 5, what is the theoretical probability of landing on a 5?

Back

1/5

In a bag with 4 green marbles, 3 red marbles, 2 blue marbles, and 1 yellow marble, what is the theoretical probability of pulling a red marble?

Back

3/10

Front

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

Back

It means the event is impossible and will not occur.

Front

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

Back

It means the event is certain to occur.

Front

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.

Front

If you flip a coin 100 times and it lands on heads 45 times, what is the experimental probability of getting heads?

Back

Experimental Probability of heads = 45/100 = 0.45.

Front

What is a favorable outcome?

Back

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