A bag contains balls which are either red, white or blue.
There are twice as many red balls as white balls.
The probability of taking a blue ball from the bag is 1/ 10

➢ Let assume that total number of balls in a bag is y.
Further,
Assume that
➢ Number of white balls in a bag is 'x'.
So,
➢ Number of red balls in a bag is '2x'.
➢ Let number of blue balls be 'z'
It is given that,
➢ Probability of getting blue ball = 1/10
We know,
So,
Also,
➢ Total number of balls = y
Now, we have
➢ Number of white balls, x = 3z
➢ Total number of balls, y = 10z
So, Probability of getting white ball is given by
