Theoretical and Experimental Probability

If you flip a coin 100 times and it lands on heads 45 times, what is the experimental probability of getting heads?

• 0.25

• 0.45

• 0.50

• 0.60

What is Theoretical Probability?

• The likelihood of an event happening based on all possible outcomes.

• The probability of an event based on past occurrences.

• The chance of an event happening in a specific situation.

• The probability that is calculated using only experimental data.

What does it mean if an event has a probability of 1?

• It means the event is certain to occur.

• It means the event is unlikely to occur.

• It means the event will never occur.

• It means the event has an equal chance of occurring or not.

If a die is rolled, what is the theoretical probability of rolling an even number?

• 1/3

• 1/4

• 1/2

• 2/3

What does it mean if an event has a probability of 0?

• It means the event is impossible and will not occur.

• It means the event is certain to occur.

• It means the event is likely to occur.

• It means the event has an equal chance of occurring or not occurring.

If a spinner is divided into 4 equal sections: red, blue, green, and yellow, what is the theoretical probability of landing on blue?

• 1/2

• 1/3

• 1/4

• 1/5

What is the formula for calculating experimental probability?

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

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

• Experimental Probability = (Number of times the event does not occur) / (Total number of trials)

• Experimental Probability = (Number of successful outcomes) / (Total possible outcomes)

What is a sample space?

• A sample space is the set of all possible outcomes of a probability experiment.

• A sample space is a collection of all the events that can occur in a probability experiment.

• A sample space is the average of all outcomes in a probability experiment.

• A sample space is a method to calculate probabilities.

What is the difference between theoretical and experimental probability?

• Theoretical probability is based on expected outcomes, while experimental probability is based on actual results from experiments.

• Theoretical probability is always higher than experimental probability.

• Experimental probability is calculated using only theoretical models.

• Theoretical probability is based on past data, while experimental probability is based on future predictions.

What is Experimental Probability?

• The probability of an event based on theoretical calculations.

• The likelihood of an event happening based on the results of an actual experiment.

• The chance of an event occurring in a perfect world scenario.

• The probability determined by historical data alone.
