Respuesta :

authenticricket
2/3 = 8/12
1/4 = 3/12
hence fraction of girls with neither blue or black eyes = 1 - 8/12 -3/12 = 1/12

Answer with explanation:

Number of girls in the class who has brown eyes [tex]=\frac{2}{3}[/tex]

 Number of girls in the class who has blue eyes [tex]=\frac{1}{4}[/tex]

Fraction of the girls in class who has neither blue or brown eyes

                         [tex]=1-\frac{2}{3}-\frac{1}{4}\\\\=1-\frac{11}{12}\\\\=\frac{1}{12}[/tex]
