Probability

1. Probability 1.1

   • Basic concepts
     • outcomes
     • sample espace
     • event
     • experiments
   • Formulas:
     • Theo:favorable outcomes/total outcomes
     • Empi:#of experiments/#favorable outcomes

2. Probability 1.3

   • Events involving "and"
     • Multiplication Rule of probability
       • idependt event
         • P(A/B):P(A)*P(B)
       • Any two event
         • P(A/B):P(B)*P(A/B)
     • conditional probabiloty formula
       • P(AyB)/P(A)

3. Probability 1.2

   • involving "not" and "or"
     • Property of Probability
       • Certan event
         • P(s)=1
       • impossible event
         • P(0)=0
       • Probability value
         • 0<P(E)<1
     • Addition rule of probability
       • If A and B are any two events, then: P(A or B)=P(A)+P(B)-P(A y B)
         • If A and B are mutually exclusive: P(A or B)= P(A) + P(B)

4. Probability 1.4

   • Venn Diagram
     • Complement
     • union
     • Difference
     • Intersection

5. Probability 1.5

   • Quantitative
     • continues
       • tiene decimales
     • discrete
       • numeros cerrados
   • Qualitative
     • All that you can not do operations
