Theoretical and Experimental Probability
Theory says a fair coin lands heads 1/2 the time. Reality says flip it 10 times and you might get 7 heads. The gap between theoretical and experimental probability — and why it narrows with more trials — is one of the deepest ideas in probability. Students explore it firsthand through experiments.
