Given, Number of white balls = 13 Let x be the number of black balls. Total number of balls in the bag = 13 + x Also, the probability of drawing a black ball from the bag is 3 times that of drawing a white ball. ⇒ x/(13 + x) = 3[13/(13 + x)] ⇒ x = 39 Hence, the number of black balls in the bag = 39.
