7th Grade- Theoretical and Experimental Probability

Front

What is probability?

Back

Probability is a measure of how likely an event is to occur, expressed as a number between 0 and 1, where 0 means the event will not happen and 1 means it will definitely happen.

Front

What is theoretical probability?

Back

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

Front

What is experimental probability?

Back

Experimental probability is the probability of an event determined by conducting experiments and observing the outcomes.

Front

How do you calculate the probability of an event?

Back

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

Front

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

Back

You would expect to get heads approximately 50 times, since the probability of heads is 1/2.

Front

What is a proportion in probability?

Back

A proportion is an equation that states that two ratios are equal, often used to predict outcomes based on known data.

Front

How do you set up a proportion to predict outcomes?

Back

To set up a proportion, you compare the ratio of successful outcomes to total outcomes in a sample to the ratio of expected outcomes to total expected outcomes.

Front

What is the expected outcome in probability?

Back

The expected outcome is the predicted number of times an event will occur based on its probability and the number of trials.

Front

What is the formula for calculating expected outcomes?

Back

Expected outcomes = (Probability of the event) x (Total number of trials).

Front

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

Back

A high experimental probability indicates that the event occurred frequently in the trials conducted, suggesting it is likely to occur again.
