A bag with 12 marbles has 5 red marbles, 3 yellow marbles, and 4 blue marbles. A marble is chosen from the bag at random. What is the probability that it is red?
Write your answer as a fraction in the simplest form.
The total number of marbles is 12. Because: 5 red marbles + 3 yellow marbles + 4 blue marbles = 12 total marbles. And there are 5 RED marbles in the special bag . . . So the probability of a red marble would be 5/12. The reason why is because there are 5 TOTAL RED marbles and there are 12 TOTAL marbles. Hope this helps!
