Answer:


P(B\lvert A)=0.222

Explanations:

Given the following probability values


\begin{gathered} P(A)=0.45 \\ P(B)=0.45 \\ P(A\text{ and B})=0.10 \end{gathered}

Required

P(B | A)

According to the conditional probability formula


\begin{gathered} P(B|A)=\frac{P(A\text{ and B})}{P(A)} \\ P(B|A)=(0.10)/(0.45) \\ P(B|A)=0.222 \end{gathered}
