Theoritical vs Experimental Probability

Theoritical Probability

We solved the problems till now using theoritical probability.
Theoretical probability describes how likely an event is to occur. We know that a coin is equally likely to land heads or tails, so the theoretical probability of getting heads is 1/2.

Experimental Probability

Experimental probability describes how frequently an event actually occurred in an experiment. So if you tossed a coin 20 times and got heads 8 times, the experimental probability of getting heads would be 8/20, which is the same as 2/5, or 0.4, or 40%.
In this case, instead of calculating using a formula, we actually throw dice multiple times and see what is the probability.
