Experimental and Theoretical Probability

What is the difference between experimental probability and theoretical probability?

• Experimental probability is based on actual experiments and outcomes, while theoretical probability is based on expected outcomes in a perfect scenario.

• Experimental probability is always higher than theoretical probability.

• Theoretical probability is determined by conducting experiments.

• Experimental probability can only be calculated in a lab setting.

What is a key characteristic of experimental probability?

• It is always equal to theoretical probability.

• It may vary from theoretical probability due to randomness and the number of trials conducted.

• It can only be determined through mathematical calculations.

• It is based solely on historical data without any trials.

Beth will reach into the bag and randomly choose 1 balloon. If there are 2 green balloons out of 5 total, what is the experimental probability she will choose a green balloon?

What is experimental probability?

• The probability determined by conducting an experiment and observing the outcomes.

• The theoretical probability based on the possible outcomes without conducting an experiment.

• The probability that is always equal to 1.

• The probability calculated by adding all possible outcomes.

How do you calculate experimental probability?

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

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

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

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