• An experiment refers to an uncertain process.


• An outcome of an experiment is a single result of that experiment.


• The sample space of an experiment is the set of all possible outcomes of that experiment. The sample
  space is denoted with the symbolSand the size of the sample space (the total number of possible
  outcomes) is denoted withn(S).


• An event is a specific set of outcomes of an experiment that you are interested in. An event is denoted
  with the letterEand the number of outcomes in the event withn(E).


• A probability is a real number between 0 and 1 that describes how likely it is that an event will occur.
