Question
A basket contains x black balls, (x + 3) white balls and (x
+ 6) yellow balls. If probability of picking a white ball is 1/11 more than that of picking a black ball, then find the probability of picking a yellow ball.Solution
ATQ,
(x + 3 – x)/(3x + 9) = 1/11
Or, 3x + 9 = 33
Or, x = 8
So, desired ratio = 14/33
