Please solve RD Sharma class 12 chapter Probability exercise 30.2 question 7 maths textbook solution

Answers (1)

Answer:

 \frac{5}{19}

Hint:

Just take events and apply probability.

Given,

            A=An even number in the 1st draw

            B= An odd number in the 2nd draw

Now,

\begin{aligned} &P(A)=\frac{10}{20}=\frac{1}{2}\\ &P\left ( \frac{B}{A} \right )=\frac{10}{19}\\ &\text { Required Probability }=P(A\cap B)\\ &=P(A)\times P\left ( \frac{B}{A} \right )\\ &=\frac{1}{2}\times \frac{10}{19}\\ &=\frac{5}{19} \end{aligned}
