Question

from a bag of red and blue balls, the probability picking a red ball is x/2. Find "x" if the probability of picking a blue ball is 2/3. ​

Answer 1

Answer:

Probability of picking blue ball is given =2/3

So probability of not picking a blue ball= 1-2/3 =1/3= probability of picking red ball=x/2

So x/2=1/3, x=2/3
