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
