Probability

1. Basic Concepts

   • Outcomes
   • Sample Space
   • Event
     • Not-Or
       • Properties
         • Certain Event
         • Impossible Event
         • Probability Value
       • Probability of the complement
       • Addition rule
     • And
       • Conditional Probability
       • Multiplication Rule
         • For any two events
         • For independent events
   • Experiments

2. Set Operations (Venn Diagrams)

   • Intersection
     • A n B
   • Difference
     • A - B
   • Union
     • A U B
   • Complemet
     • A´

3. Odds

   • a= favor b= against
     • a+b= Sample Space

4. Probability Formulas

   • Theoretical Probability Formula
     • P(E)= (# of favor outcomes) / (total number of outcomes)
   • Empirical Probability Formula
     • P(E)= (# of times that the event occurred) / (# of times that the experiment was done)
