How do I do this probability math problem, In 2000, the population of a certain country was about 195 million. The overall birth rate was 18.8 births per 100. The overall death rate was 11.8 deaths per 1000. Based on births & deaths alone(not counting immigration) how much did the population of the country increase during 2000? Thank you in advance

Ms. Sue,
Please check your numbers. The birth rate is quoted per 100 and the death rate per 1000.
Here's a start:
195 million / 100 = 1 950 000
1,950,000 * 18.8 = 36 660 000 births

AJC,
So sorry, Been up all night with this math. It is births per 1000, also. And the death rate is per 1000.
Thank you

Ms. Sue,
195 million / 1000 = 195 000
195,000 * 18.8 = 3,666,000 births
Do the same for the deaths and then subtract to find the increase in population.

AJC,
