A bag contains 10 similar balls, of which 4 are blue and 6 are red. Three balls are taken out at random from the bag one after the other without replacement. The probabilities that all the three balls drawn are red is
- A \(\frac{1}{5}\)
- B \(\frac{1}{6}\)
- C \(\frac{5}{9}\)
- D \(\frac{1}{2}\)
Answer & Solution
Correct Answer
(B) \(\frac{1}{6}\)
Step-by-step Solution
Detailed explanation
Total no. of balls \(=10\) No, of blue balls \(=4\) No. of red balls \(=6\) No. of ways to draw three red balls \(={ }^6 \mathrm{C}_3\) \(\therefore\) The required probability is :…
