Question

P(A) = 0.57, P(B) = 0.38 and P(AandB) = 0.05.P(B |A) =

Answer 1

ANSWER:

0.08771

STEP-BY-STEP EXPLANATION:

To calculate the desired probability, the following formula must be applied:

$\begin{gathered} P(B|A)=\frac{P(A\text{ and }B)}{P(A)} \\ \\ \text{ We replacing:} \\ \\ P(B|A)=\frac{0.05}{0.57} \\ \\ P(B|A)=0.08771 \end{gathered}$
