Question

I’m needing help with this question but all of the medals sums up over 400 medals overall

Answer 1

H is an empty set;

`H=\lbrace\rbrace`

Step-by-step explanation:

Given the table in the attached image.

we want to write the set H, which consists of all the countries with fewer than 400 medals.

We can observe from the table that each of the given countries has more than 400 medals.

Therefore, there is no country with fewer than 400 medals.

So, H is an empty set;

`H=\lbrace\rbrace`
