Probability - Independent Events 
The occurrence of one event does not affect the probability of the other. 
 
-If A and B are independent events, then P(A and B) = P(A)•P(B) 
 
Theoretical (Classical) Probability 
Count the number of outcomes and divide by the total possible outcomes. Theoretical probability requires that the experiment be fair. 
 
Empirical Probability (Relative Frequency) 
Perform the experiment multiple times (trials), count the number of times the event occurs and divided...
