A bag contains 2 white, 3 green and 5 red balls. If three balls are drawn one after the other without replacement, then the probability that the last ball drawn was red is

Options

  1. A2 3
  2. B3 4
  3. C5 9
  4. D1 2

Correct answer

D. 1 2

Step-by-step solution

Since, A bag has 2 white, 3 green and 5 red balls. Now, number of ways of choosing 3 ball such that last ball is red =8 9 5 So, required probability = 8 9 5 10 9 8 = 1 2 .
