      Question

      In a container holding 18 balls of three shades –

      orange, purple, and white – the probability of picking an orange ball is 1/3. If the count of white balls is twice the number of purple balls, determine the probability of selecting a purple ball.
      A 2/9 Correct Answer Incorrect Answer
      B 1/9 Correct Answer Incorrect Answer
      C 4/5 Correct Answer Incorrect Answer
      D 3/7 Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      ATQ,

      Let the number of orange balls be x. So, x/18 = 1/3 x = 6 Let the number of purple balls be y. Then, white balls = 2y Now, y + 2y = 18 – 6 3y = 12 y = 4 Required probability = 4/18 = 2/9
