Math 7 Probability and Predictions

What is experimental probability?

• Experimental probability is the probability based on historical data.

• Experimental probability is the probability that is always accurate and never changes.

• Experimental probability is the probability obtained from actual experiments or observations.

• Experimental probability is the probability calculated using theoretical formulas.

How is experimental probability calculated?

• Experimental probability = Number of favorable outcomes - Total number of outcomes

• Experimental probability = Number of favorable outcomes / Total number of outcomes

• Experimental probability = Number of favorable outcomes * Total number of outcomes

• Experimental probability = Total number of outcomes / Number of favorable outcomes

Define theoretical probability.

• Theoretical probability is the likelihood of an event occurring based on superstitions.

• Theoretical probability is the likelihood of an event occurring based on mathematical reasoning rather than empirical evidence.

• Theoretical probability is the likelihood of an event occurring based on random guessing.

• Theoretical probability is the likelihood of an event occurring based on past experiences.

What is the difference between experimental and theoretical probability?

• Experimental probability is based on theoretical calculations, while theoretical probability is based on actual outcomes.

• Experimental probability is based on actual outcomes, while theoretical probability is based on mathematical calculations.

• Theoretical probability is always accurate, while experimental probability is prone to errors.

• Experimental probability is used in controlled environments, while theoretical probability is used in real-world scenarios.
