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... 

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
