Sample Space and Probability

Front

What is Sample Space?

Back

The set of all possible outcomes of an experiment.

Front

What is Experimental Probability?

Back

The probability based on the actual results of an experiment, calculated as the number of successful outcomes divided by the total number of trials.

Front

How do you calculate Experimental Probability?

Back

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

Front

What is the difference between Experimental Probability and Theoretical Probability?

Back

Experimental Probability is based on actual experiments, while Theoretical Probability is based on expected outcomes.

If a die is rolled 60 times and the number 4 appears 10 times, what is the experimental probability of rolling a 4?

Back

Experimental Probability = 10/60 = 1/6.
