JEE Mains · Maths · STD 11 - 14. probability
Two marbles are drawn in succession from a box containing \(10\) red, \(30\) white, \(20\) blue and \(15\) orange marbles, with replacement being made after each drawing. Then the probability, that first drawn marble is red and second drawn marble is white, is
- A \(\frac{2}{25}\)
- B \(\frac{4}{25}\)
- C \(\frac{2}{3}\)
- D \(\frac{4}{75}\)
Answer & Solution
Correct Answer
(D) \(\frac{4}{75}\)
Step-by-step Solution
Detailed explanation
Probability of drawing first red and then white \(=\frac{10}{75} \times \frac{30}{75}=\frac{4}{75}\)
