not sure why you're calculating it like that

Answer 8

look at the `0-30 miles` column and `very/somewhat dangerous` row and you'll find 43%

yes but shouldn't the not 100 total(the 67) be considered?

Answer 25

D. Consider that the total number of people who drive 0 - 30 miles is 67 people. Then 24 people out of the 67 people believe that self-driving cars are very/somewhat safe. What percentage is 24 of 67 people?
