Answers (1)

Answer: 0.6

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

Given,

             P\left ( A \right )=0.3

              P\left ( B \right )=0.6

Solution:

As we know, Two events are said to be independent if the product of the events are equal to their intersection. i.e. P\left ( A\cap B \right )=P\left ( A \right )P\left ( B \right )

\begin{aligned} P\left(\frac{B}{A}\right) &=\frac{P(B \cap A)}{P(A)} \\ &=\frac{P(A) P(B)}{P(A)} \\ &=0.6 \end{aligned}
