A bag contains 14 balls out of which x are white. If 6 more white balls are added to the bag, the probability of drawing a white ball is . The value of x is: 1. 4 2. 6 3. 8 4. 10

Question

KnowledgeBoat · Accepted Answer

Given, The bag contains 14 balls. Number of white balls = x When 6 more white balls are added: New number of white balls = x + 6 Total number of balls = 14 + 6 = 20 The probability of drawing a white ball now is . ∴ 2(x + 6) = 20 x + 6 = x + 6 = 10 x = 10 - 6 x = 4 Hence, option 1 is the correct option.
