How Likely and Probability Quiz

What is experimental probability?

• Probability obtained from theoretical calculations

• Probability obtained from guessing

• Probability obtained from actual experiments or observations.

• Probability obtained from random number generation

• 0.5

• 0.3

• 0.8

• 0.2

What is theoretical probability?

• The likelihood of an event happening based on random chance.

• The likelihood of an event happening based on past outcomes.

• The likelihood of an event happening based on personal beliefs.

• Likelihood of an event happening based on all the possible outcomes.

What is the difference between experimental and theoretical probability?

• Experimental probability is based on guesses and assumptions, while theoretical probability is based on actual outcomes.

• Experimental probability is only used in scientific experiments, while theoretical probability is used in everyday situations.

• Theoretical probability is based on guesses and assumptions, while experimental probability is based on mathematical calculations.

• Experimental probability is based on actual outcomes from an experiment or trial, while theoretical probability is based on mathematical calculations and predictions.
