What does this have to do with assessing risk?

It is impossible for us help you to see your mistakes or to remove your difficulties if you tell us nothing about your work or your thoughts.

I am not at all sure what your difficulty is with respect to the first two questions. Perhaps you are wondering how you can possibly know how many were born on each day of the year. You can't; the question is idiotically worded. What it means is, if we averaged the number born on each day, how many were born on an average day. Now can you answer those first two questions.

Given the number of births in a year, you can find the average number of births each day just by dividing by 365. But it is impossible to say "how many people were born each day".

To find "births per 1000 people" you divide the number of births by the number of "thousands" of people in the country. For example it country A has "2.1 million people" it has 2,100,000 so 210 thousands of people.
