Modulo 1 (1.1-1.4)

Modulo 1 (1.1-1.4)

1. "not" and "or"

   • P(AuB)= P(A) + P(B) - P(AnB)
     • addition rule of probability
     • P(AuB) = P(A) + P(B)
       • mutually exclusive events
   • properties of probability
     • P(S) = 1
       • certain event
     • P(Ø) = 0
       • impossible event
     • 0 <= P(E) <= 1
       • probability value

2. "and"

   • multiplication rule of probability
     • P(AuB) = P(A) x P(B|A)
       • for any two events
     • P(AnB) = P(A) x P(B)
       • for independent events
   • P(B/A) = P(AnB) / P(A)
     • conditional probability formula

3. set operations

   • AuB
     • union
   • A-B
     • diferencia
   • A'
     • complement
   • AnB
     • intersection

4. probability

   • basic concepts
     • outcomes
       • possible results
     • sample space
       • all the possible outcomes
     • event
       • a single result of an experiment
     • experiments
       • an action where the result is uncertain
   • odds
     • favorable a E(a)
     • desfavorable a E(b)
     • favor (a to b)
     • contra (b to a)
   • probability formulas
     • P(E) = n(E) / n(S)
       • theoretical probability formula
     • P(E) = #veces que ocurrio evento / #veces que realizado
       • empirical probability formula
