If a bag has 7 red marbles, 5 blue marbles, 12 yellow marbles, 6 green marbles and 11 orange marbles, what is the probability that you will pick either a red marble or an orange marble?

18 / 41

Step-by-step explanation:

(red marbles + orange marbles) / total number of marbles

7 + 11 / 7 + 5 + 12 + 6 + 11

18 / 41
