1. basic concepts

   • outcomes
   • sample espace
   • event
   • experiments

2. probability formulas

   • P(E) number of times the event occurred/ number od times the experiment was performed
   • P(E) number of favorable outcomes/ total number of outcomes

3. properties of probability

   • event involving ¨not¨ and ¨or¨
     • P(A or B)= P(A) + P(B)-P(A&B)
     • mutually exclusive

4. event involving ¨ and¨

   • independientes
   • for any two events

5. Set operation

   • diagram of venn
     • P(A)´
     • P(A-B)= (X|X E A Y X ≠ B)
