Question
A bag contains ‘x’ black balls, ‘x + 2’ red
balls and ‘x + 1’ white balls. If the probability of drawing a white ball is 1/36 less than the probability of drawing a red ball, find the value of ‘x’.Solution
According to question: (x + 2)/(3x + 3) – (x + 1)/(3x + 3) = 1/36 (x + 2 – x – 1)/(3x + 3) = 1/36 1/(3x + 3) = 1/36 3x + 3 = 36 3x = 33 x = 11
