There is a jar that contains 8 marbles and 3 of them are blue. If you randomly draw 2 marbles (WITH replacement), what is the probability that both of the marbles are not blue? Write your answer as a fraction. You do not need to simplify your fraction.
The probability of drawing a non-blue marble on the first draw is 5/8 and the probability of drawing a non-blue marble on the second draw is also 5/8.
Therefore, the probability of drawing two non-blue marbles with replacement is (5/8) * (5/8) = 25/64.
