The Total solution for NCERT class 6-12
A jar contains 24marbles, some are green and others are blue. If a marble is drawn at
random from the jar,the probability that it is green is ⅔. Find the number of blue balls
in the jar.
Total marbles = 24
Let the total green marbles = x
So, the total blue marbles = 24-x
P(getting green marble) = x/24
From the question, x/24 = ⅔
So, the total green marbles = 16
And, the total blue marbles = 24-x = 8
