A student randomly chooses marbles from a bag containing 3 blue marbles and 3 red marbles. He chooses two at a time, and repeats this 10 times. The results are shown in the following table. If 2 marbles are randomly chosen, what is the probability of choosing exactly one red marble? Write your answer as a fraction in the following form n/d (no spaces).
