A bag of marbles contains 6 blue marbles, 2 yellow marbles, 4 red marbles, and 1 green marble. What is the probability of reaching into the bag and selecting a yellow marble?
2/13 because if you want to find the denominator you have to add all the marbles up to get the total amount and there are 2 yellow marble out of the 13 so the probability of picking a yellow marble would be 2/13
