They are the same

Step-by-step explanation:

One hundred draws are made at random.

The average of a list of numbers equals the sum of the numbers divided by how many numbers there are.

So, when the sum of the 100 draws is 710, the average of the draws will be

710/100 = 7.1

So, when the sum of the draws is bigger than 710, the average of the draws will be bigger than 7.1.

Therefore, the two chances are the same.
