To determine the relative frequency of boys with blonde hair, we need to follow these steps:
1. Identify the number of boys with blonde hair. According to the table, this number is [tex]\( 66 \)[/tex].
2. Identify the total number of boys. The table shows that there are [tex]\( 142 \)[/tex] boys in total.
The formula for relative frequency is given by:
[tex]\[
\text{Relative frequency} = \frac{\text{Number of boys with blonde hair}}{\text{Total number of boys}}
\][/tex]
3. Substitute the numbers we identified into the formula:
[tex]\[
\frac{66}{142} \approx 0.4647887323943662
\][/tex]
Thus, the relative frequency of boys with blonde hair is approximately [tex]\( 0.46 \)[/tex].
So, the correct answer is:
B. 0.46
