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 marble that is not blue is 5/8. Since we are drawing with replacement, the probability remains the same for the second draw.
Therefore, the probability of drawing two marbles that are not blue is (5/8)*(5/8) = 25/64.
So, the probability that both marbles drawn are not blue is 25/64.
