The content of the 3 boxes are as follows. If one box is chosen at random and three balls are drawn from it and they are all of different colours, find the probability that they come from box 2 .
Box 1 contains 1 black, 2 white, 3 red balls, and
Box 2 contains 1 black, I white, 2 red balls, and
Box 3 has 5 black, 4 white, 1 red balls.
- A \(\frac{9}{29}\)
- B \(\frac{15}{29}\)
- C \(\frac{5}{29}\)
