Theoretical and Experimental Probability Answer Key
Compare theoretical and experimental probability through simulations and discover the Law of Large Numbers.
Prior Knowledge Questions
Q1.What is probability?
Probability is the likelihood of an event occurring, expressed as a number between 0 (impossible) and 1 (certain).
Q2.What is theoretical probability?
Theoretical probability is the expected probability based on mathematical reasoning (favorable outcomes ÷ total outcomes).
Q3.What is experimental probability?
Experimental probability is based on actual results from conducting an experiment or trial.
Activity A – Coin Flips
Q1.What is the theoretical probability of flipping heads on a fair coin?
1/2 or 0.5 or 50%.
Q2.Why might experimental probability differ from theoretical probability?
Experimental probability differs due to random variation; with more trials, experimental probability gets closer to theoretical probability (Law of Large Numbers).
