Probability

1. Concepts

   • outcomes
     • sample space
       • event
         • experiments
           • number of events
           • odds
             • posibilities to win or lose
         • What you have to get
       • all the posibilities
     • results

2. formulas

   • Basic formulas
     • empirical
       • Number of times event "E" ocurred/number of time the event was performed
     • Theorical
       • P(E)=number of favorable outcomes/ total number of outcomes
     • Events involving "and"
       • Multiplication rule of probability
         • independent events
           • P(B|A)=P(B)
         • for two events
           • P(A)*P(B|A)
           • Conditional probability formula
             • P= ((P(AnB))/(P(A))
       • Events involving "not" and "or"
         • P(AuB)=P(A)+P(B)-P(AuB)
