Theoretical and Experimental Probability

Front

What is the sample space?

Back

The sample space is the set of all possible outcomes of an experiment.

Front

What is experimental probability?

Back

Experimental probability is the ratio of the number of times an event occurs to the total number of trials.

Front

What is theoretical probability?

Back

Theoretical probability is the likelihood of an event happening based on all possible outcomes.

Front

What are outcomes in probability?

Back

Outcomes are the possible results of an experiment.

Front

How do you calculate the probability of an event?

Back

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

Front

If a spinner has 3 equal sections: Red, Green, Blue, what is the theoretical probability of landing on Green?

Back

Theoretical Probability of Green = 1/3 or 33.3%.

Front

What is the probability of picking a quarter from a bag with 5 quarters, 2 dimes, and 4 pennies?

Back

Probability of picking a quarter = 5/(5+2+4) = 5/11 ≈ 0.45.

Front

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

Back

It means the event cannot happen.

Front

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

Back

It means the event is certain to happen.

Front

What is a fair spinner?

Back

A fair spinner is one where each section has an equal chance of being landed on.
