Answer:
B; 2.0%
Step-by-step explanation:
In this question, we are asked to calculate the annual percentage of death in a population that has 20 deaths out of a total of 1000 birds.
To do this, we need to divide the number of deaths over the total number of deaths and multiply by 100%
Mathematically, this can be related as follows;
20/1000 * 100 = 2000/1000 = 2%
The percentage of death in the bird population is 2%
