Probabilidad
- Probability
- Probability Formulas
- Theorical... N(E) / N(S)
- Empirical
- No. de veces que ocurre el
evento/ No. de veces que se
realizo el experimento
- No. de veces que ocurre el
evento/ No. de veces que se
realizo el experimento
- Theorical... N(E) / N(S)
- Basic Concepts
- Outcome... Exp. Effects
- Sample Espace... Conjunto
de "R" posibles
- Event... Subconjuntos
del Esp. muestral
- Experiments... Fenómeno
aliatorio
- Outcome... Exp. Effects
- Odds
- A a B .....Un numero A de los
resultados son favorables al
evento E y los restantes B son
desfavorables
- A a B .....Un numero A de los
resultados son favorables al
evento E y los restantes B son
desfavorables
- Probability Formulas
- Events involving
"not" and "or"
- Probability of the
complement
- P(E')=1- P(E)
- P(E')=1- P(E)
- Properties of
Probability
- Certain Event... P(S)=1
- Impossible Event...
P(not O)=0
- Probability Value...
0< P(E)<1
- Certain Event... P(S)=1
- Addition rule of
probability
- P(AuB) = P(A)+ P(B) - P(AnB)
- P(AuB) = P(A)+ P(B) - P(AnB)
- Probability of the
complement
- Events involving "and"
- Conditional Probability
Formula
- P(B/A)= P(AnB) / P(A)
- Probabilidad de B dado
que A ha ocurrido
- Probabilidad de B dado
que A ha ocurrido
- P(B/A)= P(AnB) / P(A)
- Multiplication Rule of
Probability
- For Independent Events
- P(AyB)=vP(A)*P(B)
- P(AyB)=vP(A)*P(B)
- For any two events
- P(AyB) = P(A)* P(B/A)
- P(AyB) = P(A)* P(B/A)
- For Independent Events
- Conditional Probability
Formula
- Set Operations
- Intersection
- (x/x E A y x E B)
- (x/x E A y x E B)
- Difference
- (x/x E A y noE B)
- (x/x E A y noE B)
- Union
- (x/x E A o x E B)
- (x/x E A o x E B)
- Complement
- (x/x E U o x noE A)
- (x/x E U o x noE A)
- Intersection
