Explanation / Answer

We are considering only the people without a college degree.

Total such people= 21+28+22=71

We require relative frequency of those who come from urban residential areas.

People without college degree from urban areas= 21

Relatively, 21/71 people who don't have a college degree come from urban areas.

This makes relative frequency=21/71=0.2957746...

Rounding up,

Answer=0.30
