Wrong. You can either drive or can't. So if 15 hs students can drive and 15 can not then there are a total of 30 students being surveyed. So there's a 50% chance that they know how to drive.

When she surveyed the college students she surveyed 60, 30 of them knew how to drive. Therefore there's also a 50% chance that the college students know how to drive.

It's wrong because the percentages are both the same.
