Answer:
The percent of the country's population with AB blood type is 9% .
Step-by-step explanation:
Given:
Recall that 1 = 100%. This means that 1 whole is 100%.
Given the percent blood types for people in a certain country:
Blood Type Percent
A 42%
B 16%
O 33%
AB AB
Now, to calculate the percent of the country's population with AB blood type:
So, getting the total percent of Blood types A, B and O:
[tex]42\%+16\%+33\%=91\%.[/tex]
Now, to get the percent of AB blood type we subtract the total percent of blood types from the whole that is 100% (as given) :
[tex]100\%-91\%[/tex]
[tex]=9\%.[/tex]
Therefore, the percent of the country's population with AB blood type is 9% .
