6% of 200 people in a medical study had a mutation in a particular gene in their DNA. How many people in this study had an unmutated gene?
To find out how many people in the study had an unmutated gene, we'll first calculate how many people had a mutated gene.
To do this, we need to find 6% of the 200 people in the study.
To calculate a percentage, we can multiply the given number (200) by the percentage value (6%) expressed as a decimal (0.06).
Let's do the math:
200 * 0.06 = 12
So, 12 people in the study had a mutation in the particular gene.
To find out how many people had an unmutated gene, we subtract this number from the total number of people in the study:
200 - 12 = 188
Therefore, 188 people in this study had an unmutated gene.
