Military medals can recognize bravery or gallantry, heroism, or meritorious service. They may be awarded for actions during peacetime or war, in defense of civilians or fellow service members, and they can be earned for actions taken during the course of combat or outside of direct military conflict.
You know that the sum of a and b is 24, because the average is the sum of the numbers divided by the amount of numbers added together, and 12*2 is 24. Add 3 to 24 so you have 27, and then divide that by 3 because there are now 3 numbers in the set. The average of a, b, and c is 9.
