Six mice are in an experiment on nutrition and 2 are chosen at random for the control group. What is the probability that the two heaviest mice are chosen for the control group?

I have no idea where to start with this problem. How do I know what the weight of the mice are to tell which one's are the heaviest? I'm so confused!!
 
Your problem is same as:

6 balls numbered 1 to 6 are in a container.
2 balls are drawn at random.
What is the probability that the 2 balls drawn are numbered 5 and 6?
