Question
A bag contains x white balls, (x + 4) black balls and (x
+ 8) yellow balls. If probability of getting a black ball is 1/12 more than that of getting a white ball, then find the probability of getting a yellow ball.Solution
ATQ,
(x + 4 – x)/(3x + 12) = 1/12
Or, 3x + 12 = 48
Or, x = 12
So, desired ratio = 20/48 = 5/12
