WebApr 1, 2024 · represents the number of white balls therefore there are 5 white balls and 10 red balls present in the bag. So, the correct answer is “Option B”. Note: Suppose if we think we have x red balls, then we have 15 − x white balls. The given condition for this can be written as ⇒ x 15 = 2 × ( 15 − x) 15 In the RHS 2 is multiplied to the numerator. WebThe correct option is A. 1235. Explanation for correct option: Calculate the Probability : Total number of balls =6+5+4=15.
