Question

Hair color is an inherited trait. In Marci's family, her mother has brown hair. Her father has blonde hair. The family has 6 children in all. Of the children 6 children,1/3 of them have blonde hair,1/6 of them have red hair, and 1/2 of them have brown hair. In simplest form, what fraction of the children has red or brown hair?

Answer 1

Answer:

the number of children has red or brown hair is $\frac{2}{3}$.

Step-by-step explanation:

We have  been  given that in Marci's family there are total 6 children.

Out of 6 children

Number of children have blonde hair = $\frac{1}{3}$

Number of children have red hair = $\frac{1}{6}$

Number of children have brown hair = $\frac{1}{2}$

Since, we have to find the fraction of children has red or brown hair=$\frac{1}{6}+\frac{1}{2}=\frac{4}{6}=\frac{2}{3}$

Hence, the number of children has red or brown hair is $\frac{2}{3}$
