there is a jar that contains 10 marbles and 4 of them are blue. If you were to randomly draw 2 marbles (with replacement) what is the probability that both of the marbles are not blue? Write your answer as a fraction
First, let's calculate the probability that one marble drawn is not blue.
There are 6 marbles that are not blue out of a total of 10 marbles. Therefore, the probability of drawing one marble that is not blue is 6/10 = 3/5.
Since we are drawing with replacement, the probabilities are independent of each other. So the probability of drawing two marbles that are not blue is (3/5) * (3/5) = 9/25.
Therefore, the probability that both marbles drawn are not blue is 9/25.
