What is the difference between theoretical probability and experimental probability?

• Theoretical probability is based on personal opinions and beliefs, while experimental probability is based on scientific evidence and facts.

• Theoretical probability is always accurate and reliable, while experimental probability is often inaccurate and unreliable.

• Theoretical probability is used in controlled laboratory settings, while experimental probability is used in real-world situations.

• Theoretical probability is based on mathematical calculations and predictions, while experimental probability is based on actual observations and data collected through experiments or real-life events.
