Experimental and Theoretical Probability

Front

What is Experimental Probability?

Back

Experimental Probability is the probability determined by conducting experiments and observing the outcomes. It is calculated as the number of successful outcomes divided by the total number of trials.

Front

What is Theoretical Probability?

Back

Theoretical Probability is the probability based on the possible outcomes in a perfect world. It is calculated as the number of favorable outcomes divided by the total number of possible outcomes.

What happens to the experimental probability as the number of trials increases?

Back

As more trials are completed, the experimental probability generally draws closer to the theoretical probability.

What is a likely chance event closer to?

Back

A likely chance event is closer to 1.

How do you calculate Experimental Probability?

Back

Experimental Probability = (Number of Successful Outcomes) / (Total Number of Trials)

Front

What is the formula for Theoretical Probability?

Back

What is the range of probability values?

Back

The range of probability values is from 0 to 1, where 0 means an event will not happen and 1 means an event will certainly happen.
