Choose a binomial probability experiment. You could flip a coin, or toss a basketball from the free throw line and see if you make the shot or miss, or choose another experiment where the outcome is a success or failure (only two possible outcomes.)
1) Make a guess about the probability of success before doing the experiment.
2) Repeat the experiment 50 times, and record the results.
3) Calculate the empirical probability of success, and compare it to your original guess. Were you close or were you far off?
4) Write a paragraph explaining how you did the experiment and comparing your results to your guess.
