Rule 4 throw me off. It says

J drives on Wednesdays or Saturday or both, and he may also drive on other days

So basically J can be weds or Sat or both ...which I get. But if J is not both rule is therefore violated correct?



Diagram would be

IF J is not on 3-> J is on 6
If J is not on 6 -> J is on 3

?

I don't think this is a not both rule.
He can drive on Wednesday or he can drive on Saturday. Or he can drive on both Wednesday or Saturday. OR he can drive on Wednesday, Saturday, and many other days of the week.
It's an "or" statement. Not a not both statement.

Maybe you should review this lesson:
http://7sage.com/lesson/clarification-for-either-or/

The rule as it is written implies an INCLUSIVE "or." The big hint that enables you to infer this the inclusion of the word "BOTH" at the end. So it just as @harrismegan said, but perhaps an easier way for you to think about it could be:
Since Rule #1 states that every person drives on at least one day, J must drive AT LEAST on Wednesday or on Saturday.
Thus:
If J only drives on Wednesday, that's okay.
If J only drives on Saturday, that's also okay.
If J drives on Wednesday AND Saturday, that's also okay.
If J drives on Thursdays, that's NOT okay.
If J drives on Wednesdays and Thursdays, that's okay.
If J drives on Fridays, that's NOT okay.
If J drives on Saturdays and Fridays, that's okay.

As far as I know (someone please correct me if I'm wrong), the only times it will be a "not both" is when it explicitly says "Not Both" in the rule, or if the game setup itself implies that (just like an In-Out Grouping Game). Sorry for my wordiness, I figured that clarity takes precedence over brevity...

Good luck!
