Group 4 Negate, Necessary

Maestro_eba

The example given on the cheat sheet states, No candy is bitter.
pick either idea and negate it right?
what about No candy? doesn't that mean candy is negated?
so instead of C arrow /B shouldn't it be /C arrow /B?

You pick one of the variables, candy or bitter, negate it, and it becomes the necessary condition.

No candy is bitter=
C-->/B
B-->/C

thanks, but my question is why isn't it /C-->B?
or did u already negate the C?
thanks for your help

@Maestro_eba He answered it. You're negating the sufficient condition (the left side of the arrow). Group 4 negates the necessary condition (the right side of the arrow). This is all explained very well in the 7Sage curriculum. I'd advise the starter package if you're not 100% certain with your logic. Worth every penny.
