A bag contains 3 red marbles, 5 yellow marbles, and 4 blue marbles. One marble is chosen at random. What is the probability that the chosen marble will be blue?
Hey! So I know you know the answer but I felt you should know how to work it... First add all the marbles together (4+3+5=12). Then put the color you want over the total amount (in this case it would be 4: 4/12). Then simplify: 4/12=1/3 :) I hope this helps
