Question

A bag contains 4 white and 5 blue balls. They are mixed thoroughly and one ball is drawn at random. What is the probability of getting (i) a white ball? (ii) A blue ball? Select the correct answer from above options

Answer 1

(i) We know that the bag containing the total balls = 4white + 5blue = 9ballsWhite balls = 4 By using the formula, Probability p () = number of favorable outcomes/ total number of outcomes ∴ Probability of getting a white ball p (W) = number of white balls/total number of balls =4/9 (ii) We know that the bag containing the total balls = 4white + 5blue = 9ballsBlue balls = 5 By using the formula, Probability p () = number of favorable outcomes/ total number of outcomes ∴ Probability of getting a blue ball p (B) = number of blue balls/total number of balls =5/9
