Hello guys, can you please help my son!!

Based on the fact that there is no country which had won more than 900 silver medals, set E using the roster method would be E = { }.
Set E is meant to include the set of countries who have attained more than 900 silver medals in the Olympic games.
The highest number of silver medals attained is that of the United States which is 860 silver medals.
This means that no single country has attained more than 900 silver medals.
Set E would therefore be null. Using the roster method, the way to show set E would be:
E = { }
In conclusion, set E is E = { }.
