REMA DE BAYES egla de Bayes, es solo una técnica para calcular probabilidades condicion a expresión \( P(B / A) \), la regla de Bayes, indica que el suceso \( B \) ha ocy ál es la probabilidad de que provenga de \( A \) ? Cual es la probabilidad de causa de \( B \) ? Lo que implica determinar \( P(B / A) \). \[ P(B / A)=\frac{P(B) * P(A / B)}{P(B) P(A / B)+P(B) P(A / B)} \]
