Exploring Theoretical and Experimental Probability

What does a uniform probability model imply about the outcomes?

• Each outcome has a different probability.

• Outcomes are based on physical measurements.

• Each outcome has an equal probability of occurring.

• Outcomes are unpredictable.

If a coin is flipped 100 times, how many times should it theoretically land on heads?

• 25 times

• 50 times

• 75 times

• 100 times

What does experimental probability rely on?

• Relative frequency based on actual data

• Theoretical calculations

• Predictions without data

• Fixed outcomes

In the spinner example, what was the experimental probability of landing on red?

• 0.2

• 0.4

How does the experimental probability of spinning red compare to its theoretical probability?

• It is higher

• It is lower

• It is the same

• Cannot be determined
