Question

a bag contains in all 50 balls some of them are white summer blue and summer read the number of white balls is 11 times the number of Blue Balls the number of red balls is less than the number of white balls also the number of red balls is more than the number of Blue Balls if one of the balls is selected at random from the bag what is the probability that is it is red

Answer 1

Answer: 0.28

Step-by-step explanation:

Let number of blue balls = x

then number of white balls = 11x

By hit and trial method we can find x = 3 (as if x =1 then white ball = 11, blue ball = 1, red ball = 50-1-11 = 38,similarly not true for x = 2 also)

Now, number of red balls = 50 - 3 - 33 = 14

P(drawing a red ball) = 14/50 = 0.28
