Encontrar P(A∩B) dos eventos dependentes A e B

$P (A) = 0.2$ , $P (B) = 0.09$ , $P (B g i v e n A) = 0.03$

Etapa 1

Quando $A$ e $B$ são eventos dependentes, a probabilidade de $A$ e $B$ ocorrerem é $P (A \cap B) = P (A) \cdot (P (B | A))$ , que é a chamada regra da multiplicação para eventos dependentes $A$ e $B$ .

$P (A \cap B) = P (A) \cdot (P (B | A))$

Etapa 2

Preencha os valores conhecidos.

$P (A \cap B) = 0.2 \cdot 0.03$

Etapa 3

Multiplique $0.2$ por $0.03$ .

$P (A \cap B) = 0.006$
