There is a jar that contains
8
8 marbles and
5
5 of them are blue. If you were to randomly draw 2 marbles (with replacement) what is the probability that both are the marbles are not blue? Write your answer as a fraction. You do not need to simplify your faction.
The probability of drawing a non-blue marble on the first draw is
3/8
3
/
8
.
Since we replace the marble after each draw, the probability of drawing another non-blue marble on the second draw is also
3/8
3
/
8
.
Therefore, the probability of drawing two non-blue marbles in a row is
(3/8)*(3/8) = 9/64
So, the probability of drawing two marbles that are not blue is
9/64.
