Compute and compare theoretical and experimental probability in simple settings.
Find experimental probability
Problem
A coin landed heads \(13~\text{times}\) in \(20~\text{flips}\). Calculate the experimental probability of heads as a fraction.
Big Picture
What this problem is really about
Experimental probability describes what actually happened, so use the recorded heads as the success count and all flips as the trial count. Put observed successes over total trials, then check whether the fraction reduces. The coin's two possible sides determine a theoretical probability, but they are not the denominator for this experiment.
