Experimental Probability Flashcard

What is experimental probability?

Back

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

Front

How do you calculate experimental probability?

Back

Experimental probability = (Number of successful outcomes) / (Total number of trials).

What does it mean if an experimental probability is close to 1?

Back

It means the event is very likely to occur based on the experimental results.

What does it mean if an experimental probability is close to 0?

Back

It means the event is very unlikely to occur based on the experimental results.

How can you express experimental probability as a percentage?

Back

Multiply the experimental probability (as a fraction) by 100.
