Answer:

1/2

Explanation:

To find the probability, you need to put the number of what you want to know the probability of over the total. In this case, we want to know what the probability of red and green over the total is. So, hence the equation:


(5+1)/(12) or
(6)/(12) which can be simplified to
(1)/(2).
