Experiment: is a planned operation carried out under the controlled condition
Outcome: Result of an experiment
Sample space: a set of all possible outcomes
Event: any combination of outcomes that are usually represented by the letters A and B.
Equally Likely: Each outcome of an experiment has the same probability.
Probability: the chance of the outcome of an event
“OR” Event: an outcome is in the event A OR B if the outcome is in A or is in B or is in both A and B.
"AND" Event: an outcome is in the event A AND B if the outcome is in both A and B at the same time.
Conditional probability: A given B is written P(A|B). P(A|B) is the probability that event A will occur given that event B has already occurred
Complement: A given B is written P(A|B’)
