an Experiment is a controlled operation that yields a set of results.
The possible results of an experiment are the outcomes
A collection of outcomes is called an event
Empirical Probability is derived by counting the relative number of times en event occurs to the number of trials conducted.
Theoretical probability is derived from a study of the possible outcomes.
Empirical probability formula
Number of time E occurred
P(E) = -----------------------
Total number of trials

Do 18, 20, 22
Law of large numbers probability statements apply in practice to
a large number of trials, not a single trial. It is the relative frequency over the long run that is accurately predictable, not individual events or precise totals.
