If a population of 1,000 has a disease prevalence of 3%, how many individuals are expected to be affected? (2019)

Step 1: Understand the problem. We need to find out how many people in a population of 1,000 have a disease that affects 3% of the population.
Step 2: Convert the percentage to a decimal. 3% as a decimal is 0.03 (you do this by dividing 3 by 100).
Step 3: Multiply the decimal by the total population. So, we calculate 0.03 (the decimal) times 1000 (the population).
Step 4: Perform the multiplication. 0.03 × 1000 = 30.
Step 5: Conclusion. This means that 30 individuals are expected to be affected by the disease in a population of 1,000.
