What's the formal logic for this rule?

Postby logicgamesbrah » Mon Nov 01, 2010 8:32 pm

I seem to be blanking here.

Either A or B must be with C.

Is it, if C > A or B?

C ---> CA or CB
not A and Not B --> not C

C => A or B

Then by negation:

xA and xB => xC

Edit: Poster above me got to it first.
