A jar contains 24 marbles, some are green and others are blue. If a marble is drawn at random from the jar, the probability that it is green is. Find the number of blue balls in the jar.

Total number of marbles = 24

Let the
total number of green marbles be *x*.

Then,
total number of blue marbles = 24 − *x*

P (getting a given marble)

According to the condition given in the question,

Therefore, total number of green marbles in the jar = 16

Hence,
total number of blue marbles = 24 − *x* = 24 − 16 =
8
