Answers (1)

Answer:   \frac{2}{5}

Given:

If 

\begin{aligned} 4 \mathrm{P}(\mathrm{A}) &=6 \mathrm{P}(\mathrm{B}) \\ &=10 \mathrm{P}(\mathrm{A} \cap \mathrm{B}) \\ &=1 \end{aligned}

Then P\left (\frac{A}{B} \right )=...

Hint:

P\left(\frac{A}{B}\right)=\frac{P(A \cap B)}{P(B)}

Explanation:

\begin{aligned} &4 \mathrm{P}(\mathrm{A})=10 \mathrm{P}(\mathrm{A} \cap \mathrm{B}) \\ &\Rightarrow \frac{\mathrm{P}(\mathrm{A} \cap \mathrm{B})}{\mathrm{P}(\mathrm{A})}=\frac{4}{10} \\ &\Rightarrow \mathrm{P}\left(\frac{\mathrm{B}}{\mathrm{A}}\right)=\frac{4}{10} \\ &=\frac{2}{5} \\ &\Rightarrow \mathrm{P}\left(\frac{\mathrm{B}}{\mathrm{A}}\right)=\frac{2}{5} \end{aligned}
