Differences between Theoretical Probability and Experimental Probability

Topic : Theoretical Probability and Experimental Probability

Question : "Theoretical Probability" and the differences between "Theoretical Probability and Experimental Probability"

Answer :
Theoretical probability is the chance of an event happening as determined by calculating the mathematical result.
Experimental probability is the chance of an event happening based in repeated testing or observation

For example, if I flip a coin the theoretical probability of a Heads is 1 / 2
whereas the experimental probability is often quite different.
When the number of experiments increase(quite a big number) the experimental probability in the absence of any other bias tends to match the theoretical probability.
