# A jar contains 24 marbles. Some are red and others are white. If a marble is drawn at random from the jar, the probability that it is red is 2/3, then the number of white marbles in the jar is:

Let the number of white marbles be x.

Since only two color marbles are present, and total probability we know of all the events is equal to 1.

P (white) = 1 – P (red)

x/24 = 1 – (2/3)

x/24 = 1/3

x = 8

Hence the number of white marbles are 8.
