Experimental Probability

What is experimental probability?

Back

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

Front

How do you calculate experimental probability?

Back

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

What is the total number of outcomes when rolling a die?

Back

6 (the numbers 1 through 6).

Front

What does it mean if the experimental probability of an event is close to the theoretical probability?

Back

It suggests that the experiment is accurately reflecting the expected outcomes based on probability theory.
