there is a jar that contains 8 marbles and three of them are blue. If you randomly draw 2 marbles (WITH replacement) , what is the probability that both of the marbles are not blue? Right or answer as a fraction
The probability of drawing a blue marble on any one draw is 3/8. Therefore, the probability of not drawing a blue marble on any one draw is 1 - 3/8 = 5/8.
Since there is replacement, the probability of drawing two marbles that are not blue is (5/8)(5/8) = 25/64.
Therefore, the probability that both marbles drawn are not blue is 25/64 or approximately 39.1%.
