Answer

Explanation:

Step1: Calculate percentage of girls with blonde hair

The number of girls with blonde hair is 6 and the total number of students is 40. The percentage formula is $\frac{\text{Number of girls with blonde hair}}{\text{Total number of students}}\times100%$. So, $\frac{6}{40}\times 100% = 15%$.

Step2: Find number of boys with red hair

From the table, the number of boys with red - hair is 2.

Step3: Calculate the probability of a boy with black hair

The number of boys with black hair is 4 and the total number of students is 40. The probability formula is $\frac{\text{Number of boys with black hair}}{\text{Total number of students}}$. So, $\frac{4}{40}=\frac{1}{10}=0.1$ or $10%$.

Answer:

The percentage of students that are girls with blonde hair is 15%. The number of students who are boys with red hair is 2. The chance that a student in the class is a boy with black hair is 10%.
