A jar contains 3 red marbles, 8 green marbles and 12 white marbles. If a marble is drawn from the jar at random, what is the probability that this is white?
it should be 12/23 but i dont see the answer in the multiple choice, if its a miss type and its 4 red marbles or 9 green or 13 whit then it should be C.

you suppose to add all of the numbers like 3+8+12=23 and because your finding the probability of getting white marbles which has 12 pieces you'll put it on divisor
