Question
A bag contains 25 white and some black balls. If the
probability of drawing a black ball from the bag is 1.4 times that of drawing a white ball, find the number of black balls in the bag.Solution
Given, Number of white balls = 25 Let x be the number of black balls. Total number of balls in the bag = 25 + x Also, the probability of drawing a black ball from the bag is 1.4 times that of drawing a white ball. ⇒ x/(25 + x) = 1.4[25/(25 + x)] ⇒ x = 35 Hence, the number of black balls in the bag = 35.
