Theoretical and Experimental Probability

The video tutorial covers theoretical and experimental probability, explaining their definitions and differences. It demonstrates how to conduct experiments to compare theoretical and experimental probabilities, showing that more trials lead to closer alignment. The concept of relative frequency is introduced, and a practice problem is solved to predict outcomes using theoretical probability.

What is the main objective of learning about theoretical and experimental probability?

• To understand the difference between them

• To memorize probability formulas

• To learn about probability history

• To calculate exact outcomes

In theoretical probability, what is the probability of landing on a specific color if a spinner is divided into 5 equal sections?

• 1/2

• 1/5

• 1/3

• 1/4

How is experimental probability determined?

• By theoretical calculations

• By guessing the outcomes

• By using a formula

• By conducting an experiment and recording results

What happens to experimental probability as the number of trials increases?

• It becomes less accurate

• It becomes unpredictable

• It becomes more likely to match theoretical probability

• It remains the same

What is relative frequency?

• The difference between two probabilities

• A random guess

• The number of times an outcome occurs divided by total outcomes

• Theoretical probability

If a spinner with 8 equal sections is spun 4800 times, how many times would you expect it to land on a section with a 1/8 probability?

• 800 times

• 480 times

• 600 times

• 1000 times

What is the expected number of times a spinner will land on blue if there are 3 blue sections out of 8 and it is spun 4800 times?

• 600 times

• 2400 times

• 1800 times

• 1200 times

What is the relationship between relative frequency and experimental probability?

• They are equal

• Relative frequency is always higher

• Relative frequency is always lower

• They are unrelated

Why is it important to conduct a large number of trials in an experiment?

• To make the experiment more complex

• To ensure the results are random

• To increase the likelihood of matching theoretical probability

• To decrease the time taken

What is the theoretical probability of landing on a specific color if a spinner is divided into 8 equal sections?

• 1/8

• 1/4

• 1/6

• 1/2
