A marketing firm wants to know how many people in District 6 have tried Popeyes' and Chick-fil-A's chicken sandwiches. Of the 10,000 people in District 6, 1500 are vegetarians or vegans and have never tried either sandwich, 5000 have tried both, and the rest have tried one or the other. What is the population proportion for people who have tried both sandwiches?

-0.50

-0.45

-0.30

-0.15

You clearly state that 5000 of the 10,000 have tried both.
The you ask what proportion have tried both sandwiches
obviously that would be 5000/10000 or 1/2
as a percentage it would be 50%, as a decimal .5

The rest of the data in your question appears to be just "white noise"
