There are 6 brown, 5 blue, and 2 orange marbles in a hat. What is the probability of picking two orange marbles in a row without returning the marbles back to the hat? (Write your answer as a fraction.)
Hi, I don't know if this is right but I would put 2/13 as the answer. This is because there are 13 marbles in total and 2 are orange. It's probably wrong, but that's what I think...
