A jar contains 24 marbles, some are green and other are blue. If a marble is drawn at random from the jar, the probability that it is green is 23. and 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) \( = \ \frac{x}{24} \)

From the question, \( \frac{x}{24} \ = \ \frac{2}{3} \)

So, the total green marbles = 16

And, the total blue marbles = 24 - x = 8
