To find the probability that someone aged 15-16 prefers biking, we need to look at the number of 15-16 year olds who prefer biking and divide that by the total number of 15-16 year olds.
From the table:
- Number of 15-16 year olds who prefer biking: 47
- Total number of 15-16 year olds: 180
The probability \( P \) that a randomly selected 15-16 year old prefers biking can be calculated as follows:
\[ P(\text{biking | 15-16}) = \frac{\text{Number of 15-16 year olds who prefer biking}}{\text{Total number of 15-16 year olds}} = \frac{47}{180} \]
Now, let's calculate this value:
\[ P(\text{biking | 15-16}) \approx 0.2611 \]
To convert this probability into a percentage:
\[ 0.2611 \times 100 \approx 26.11% \]
Rounding this value gives us approximately 26%.
Therefore, the probability that someone who is 15-16 years old prefers biking is 26%.
The correct response is:
26%
