Question

5) A bag contains 8 red balls and some blue balls. If one ball is drawn randomly the probability of drawing a ball to a blue ball are in the ratio 5 : 2, determine the probability of drawing a blue ball from the bag.​

Answer 1

Answer:

Total balls in bag = (8 + x) . → x = (16/5) . therefore, → The probability of drawing a blue ball from the bag = (16/5) / (16/5 + 8) = (16/5) / (56/5) = (16/56) = (2/7) (Ans.)
