What is Theoretical Probability  Theoretical Probability Is what you predict what will happen without really doing the experiment.  I have a number cube and a coin.  What can you predict what you would get if you tried 20 times with this experiment ?  12 total outcomes.

T heoretical Probability 1 st event2 nd event heads st event2 nd event Tails

What is Experimental Probability?  Experimental Probability is when you actually test your experiment.  So if I actually tried my experiment 24 times, how many total outcomes could there be?  24 total outcomes.
