A bag contains only 3 different colours and atleast one ball of red, white and blue colour. If the number of balls of each colour is distinct and red coloured balls are more than each of the other two colours, what is the probability of picking red ball?
(1) number of blue and white ball is half of total number of ball.
(2) there are 3 red coloured balls.

Hi,
I think it's D.
For statement 2:
Though the total number of balls was not mentioned, We can estimate the number of blue and white balls from the condition given in the question "the number of balls of each colour is distinct and red coloured balls are more than each of the other two colours".
So, the only possibility is that the number of blue and white colour balls are 2 and 1.
Then the probability of selecting a red ball is again 1/2.
Please post OA.
