To find the probability that a 15-16 year old will prefer biking, you would use the following formula:
P(Biking | 15-16 years old) = Number of 15-16 year olds who prefer biking / Total number of 15-16 year olds
From the table, the number of 15-16 year olds who prefer biking is 47.
Total number of 15-16 year olds is 180.
P(Biking | 15-16 years old) = 47 / 180 ≈ 0.2611 or 26.11%
Therefore, the probability that a 15-16 year old will prefer biking is approximately 26.11%. The closest response option is 26%.
