What is Experimental Probability?

Back

Experimental Probability is the probability of an event occurring based on the results of an experiment or trial, calculated as the number of times the event occurs divided by the total number of trials.

How do you calculate Experimental Probability?

Back

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

In an experiment where a die is rolled 12 times, if a 4 is rolled 2 times, what is the experimental probability of rolling a 4?

Back

P(4) = 2/12 = 1/6

The spinner was spun 30 times and landed on blue 12 times. What is the experimental probability of landing on a color that is not blue?

Back

P(Not Blue) = (30 - 12) / 30 = 18/30 = 3/5

What is the difference between theoretical probability and experimental probability?

Back

Theoretical probability is based on expected outcomes in a perfect world, while experimental probability is based on actual results from experiments.

Front

What is the sample space when rolling a die?

Back

The sample space is {1, 2, 3, 4, 5, 6}.

If an event has occurred 5 times out of 20 trials, what is the experimental probability of that event?

Back

P(Event) = 5/20 = 1/4
