Theoretical & Experimental

Front

What is Theoretical Probability?

Back

Theoretical Probability is what should happen in an ideal situation.

Front

What is Experimental Probability?

Back

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

Front

If a die is rolled 20 times and a '5' appears 15 times, what is the experimental probability of rolling a '5'?

Back

The experimental probability of rolling a '5' is 3/4.

Front

If Neil tossed a die 90 times and the number '1' appeared 13 times, what is the experimental probability of rolling a '1'?

Back

The experimental probability of rolling a '1' is 13/90.

Front

If an arrow is spun 15 times and lands on section Q 4 times, what is the experimental probability of landing on Q?

Back

The experimental probability of landing on Q is 4/15.

Front

What is the formula for calculating Experimental Probability?

Back

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

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 outcomes from experiments.

Front

If a spinner is spun 200 times and lands on '3' 50 times, what is the experimental probability of landing on '3'?

Back

The experimental probability of landing on '3' is 50/200 or 1/4.

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 and will definitely occur.
