Using proportions, it is found that 7% of the population has blue eyes without blonde hair.

10% of the population has blue eyes. These 10% are composed by:

  • 75% of 4%(have blonde hair).
  • x% of 96%(do not have blonde hair)

Hence, the relation according to the proportion of 10% is:

0.75(0.04) + 0.96x = 0.1

x = \frac{0.1 - 0.75(0.04)}{0.96}

x = 0.0729

Out of the entire population:

0.0729(0.96) = 0.07

7% of the population has blue eyes without blonde hair.
