Calculo probability

Calculo probability

1. Basic Concepts

   • Outcomes: the possible results of an experiment
   • Sample space: All possible outcomes
   • Event: Any such subset of the sample space
   • Experiments: Any observation

2. Odds

   • Odd in favor a to b
   • Odd against b to a

3. Formulas

   • P(E)=favorable/total outcomes
   • P(E)=times ocurred/total

4. Not and or

   • P(AuB)=P(A)+P(B)-P(AnB)
   • P(AuB)=P(A)+P(B)

5. And

   • P(B|A)=P(AnB)/P(A)

6. Set operations

   • Intersection (n)
   • Union (u)
   • Complement (')
   • Difference (-)
