A bag contains red, blue and green balls. It is twice as likely to pick a blue ball as compared to a red ball, and it is thrice as likely to pick a green ball as compared to a red ball. What is the probability of picking a green ball?
Let P (Red) = x
Then, P (Blue) = 2x and P (Green) = 3x
x + 2x + 3x = 1 (Because the sum of probabilities of all outcomes is 1)
x = 16.
P (Green) = 36 = 12.
