I had some trouble with this one and the key was recognizing the following:
- tiny fraction of people have radar detectors E.g, if there are 100 total drivers, only 3 are RD
- 1/3 of all the people who get tickets are the RDs. E.g, so our 3 dudes are getting alot of the tickets!
- conclusion - well, people with the rd must be speeding regularly.
I missed the key word "regularly"
A) This does not help the conclusion, it is actually against it. our 3 dudes are getting lots of tickets!
