Theoretical vs Experimental Probability

The video tutorial introduces the concepts of theoretical and experimental probability, explaining their differences and how to calculate each. It demonstrates these concepts through a coin-flipping experiment, showing how experimental results can differ from theoretical expectations. As more trials are conducted, the experimental probability tends to align more closely with the theoretical probability. The tutorial concludes with key insights on the importance of sample size in probability experiments.

What is the main focus of the probability unit discussed in the video?

• Theoretical probability only

• Experimental probability only

• Theoretical versus experimental probability

• Probability of complex events

What does theoretical probability rely on?

• Random guesses

• Mathematical calculations and expectations

• Past experiences

• Actual outcomes of an experiment

How is experimental probability determined?

• By predicting outcomes before an experiment

• By calculating expected outcomes

• By observing actual outcomes during an experiment

• By using historical data

What is the key difference between theoretical and experimental probability?

• Theoretical probability is based on expected outcomes, while experimental probability is based on actual outcomes

• Experimental probability is more reliable

• Theoretical probability is always accurate

• Experimental probability is based on predictions

In a small sample size experiment, what was the observed experimental probability of landing on heads?

• 50%

• 80%

• 20%

• 60%

How did the experimental probability change when the sample size increased to 50 trials?

• It got closer to the theoretical probability

• It remained the same

• It became less accurate

• It became more random

What was the result of the experiment after 100 trials?

• The experimental probability was 75%

• The experimental probability was unpredictable

• The experimental probability was still far from theoretical probability

• The experimental probability was exactly 50%

What is the key takeaway about the relationship between sample size and probability accuracy?

• Larger sample sizes lead to more accurate experimental probabilities

• Smaller sample sizes are more reliable

• Sample size does not affect probability accuracy

• Probability accuracy decreases with larger sample sizes
