Theoretical probability<span> is the term used to describe what </span>we<span> expect to happen based on math theory, whereas </span>experimental probability<span> refers to what actually happens when the actual situation </span>is tried out as an experiment.
We can relate the two types of probability by comparing their values - the values should be relatively close. In most experiments, they will not be equal, but they should be relatively close; if not, it may be that the experiment was conducted improperly or more trials need to be completed.
