This video tutorial explains the concepts of theoretical and experimental probability, using examples like coin flips and spinner experiments. It guides students through conducting experiments to compare theoretical predictions with actual outcomes, emphasizing the role of relative frequency in approaching theoretical probability as the number of trials increases.

What does experimental probability measure?

• The likelihood of an event based on past events

• The ratio of successful outcomes to possible outcomes

• The predicted outcome of an event

• The ratio of times an event occurs to the total number of trials

What is the theoretical probability of the spinner landing on a heart?

• 4/7

What does relative frequency approach as the number of trials increases?

• A constant value

• The sum of all probabilities

• The theoretical probability

• It becomes less accurate

• It remains the same

• It becomes more accurate

After spinning the spinner 100 times, what pattern is likely observed?

• The experimental probability exceeds the theoretical probability

• The experimental probability gets closer to the theoretical probability

• The experimental probability becomes less predictable

• The experimental probability remains constant
