Aproximacion Normal Binomial Poisson

En la practica se utiliza la aproximación de Binomial a la Normal cuando :
n>=30, np>=5, nq>=5
La Binomial podemos aproximarla a una distribución de Poisson donde el número de pruebas es muy alto, pero la probabilidad de éxito muy baja
si n>50 y p<0.1 y np<5
La de Poisson la podremos aproximar a la Normal si np>5
No olvidar las correcciones por continuidad.
