Abag contains 40 marbles: 12 red, 12 blue, and 16 yellow. what is the probability that a blue is randomly selected? a) .30 b) .33 c) .40 d) .60

Unlike Abby, I actually did more math then just adding up all the numbers. It will be a 40% chance to pull out a yellow marble, not a blue one. The correct answer is A, 30%. 30% times 40(marbles) = 12(number of blue marbles). So the answer is A, 30%. I would really appreciate it if you have me brainliest, knowing that I actually got you the right answer and didn’t just add.

Main idea on left, details on right
