What percentage of babies have Brown and Blue eyes?

blue=2%

Explanation:

The explanation by the paragraph it is said (to find the percent divide the total number of blue-eyed by the total number of babies born) 20÷10 =2 . The answer is 2%

Answer:

In fact, a 2016 Stanford University study involving 192 newborns found that nearly two-thirds of them were born with brown eyes, while only about 1 in 5 babies arrived with blue eyes. The Stanford researchers also noted, however, that the majority of babies in the study born with blue eyes were Caucasian
