Solution

The correct option is B 15%
$Probability = \frac{N u m b e r o f f a v o r a b l e o u t c o m e s}{T o t a l n u m b e r o f o u t c o m e s}$

Total number of outcomes = 20 +12 + 30 + 18 = 80

So, the probability of people in the age $group 16 to 30 = \frac{12}{80}$

= 0.15 = 15%

Hence, the likelihood that the visitor is from the age group of 16 to 30 is 15%.
