Experimental and Theoretical Probability

Front

What is experimental probability?

Back

Experimental probability is the probability of an event based on the results of an actual experiment or trial. It is calculated by dividing the number of times an event occurs by the total number of trials.

What is theoretical probability?

Back

Theoretical probability is the probability of an event based on the possible outcomes in a perfect world. It is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

What is a sample space in probability?

Back

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

Front

What is an event in probability?

Back

An event is a specific outcome or a set of outcomes from a probability experiment.

Front

What does it mean if an event is certain?

If a guest is more likely to choose chicken over vegetarian, what does this imply about their choices?

Back

This implies that the probability of choosing chicken is greater than the probability of choosing vegetarian.

Front

What does it mean if a guest is three times as likely to choose one option over another?

Back

It means that the probability of choosing that option is three times greater than the probability of choosing the other option.
