400
What does experimental probability mean?
What actually happened after doing the experiment.
Example: Steven flips a coin 40 times. It landed on heads 25 times and tails 15 times. The theoretical probability of the coin landing on heads is 20/40 or 1/2 (that is what it should be), BUT the experimental probability is that the coin landing on heads 25/40 or 5/8 of the time. (What actually happened)
