The percent of the population that would test positive for the disease is 15.6%.

What is a percentage?

A percentage represents a rate out of one hundred.

How to calculate the percentage?

First, determine the percent of the population with the disease that would test positive:

  • Percentage of the population with the disease: 7% or 0.07
  • Probability of testing positive: 90% or 0.9
  • Probability of testing positive if you have the disease: 0.07 x 0.9 = 0.063

Then, determine the percent of the population without the disease that would test positive.

  • Percentage of the population without the disease: 93% or 0.93 (100 - 7 = 93)
  • Probability of testing positive: 10% or 0.1 (100 - 90 = 10)
  • Probability of testing positive if you do not have the disease: 0.093

Finally, add the percentages or probabilities.

0.063+0.093 = 0.156 or 15.6%
