Given : A jar contains 24 Marbles,
some are green and some others are blue,
a marble is drawn at random from the jar, the probability that of that green is 2/3
To find : the number of blue balls in the jar.
Solution:
jar contains 24 Marbles,
Blue Marbles = B
Green Marbles = 24 - B
Probability of Drawing Green Marble = (24 - B)/24
Probability of Drawing Green Marble = 2/3
Equate
(24 - B)/24 = 2/3
=> (24 - B) = 16
=> B = 8
number of blue marbles = 8
