As used in the field of science, experimental probability, and theoretical probability, the two major components of probability. In calculating experimental probability, you are to divide the outcome by the number of trials or attempts.
For example, if Peter tossed a coin 7 times and obtains 4 heads and 3 tails, the experimental probability of acquiring ahead is 4 out of 7. Theoretical probability, on the other hand, is calculated by finding the ratio between the favorable outcome and the possible outcome.
For example, if there are 2 black balls, 3 blue balls, and 5 brown balls in a basket, the theoretical probability that John would pick a blue ball is 3 ratio 10. Theoretical probability is usually used in businesses and some kinds of researches, while experimental probability is often used in scientific and medical research. However, experimental probability looks simpler than theoretical probability.
