A bag contains 5 red marbles, 7 green marbles, and 3 yellow marbles. If a marble
is drawn at random, what is the probability that the marble will be yellow?
The answer will be A 1/5 because you add to find the total. Which is 15. The are 3 marbles so the probability will be 3/15 and if you simplify it by dividing each the numerator and denominator by 5 it would 1/5.
