Question

A bag contains 5 red balls and some blue balls,if the probability of drwaing a blue ball

Answer 1

Let the blue balls be denoted by 'x'
Therefore,
Probability = Possible Outcomes/ Total No. of outcomes
= x/5+x
That's all information that can be given for the q.

Answer 2

let the no. of blue balls =X
so, Total no. of balls = 5+X

probability of drwaing blue ball = X/5+X
