Diagramming Answer C to Question 23

Hi! I'm a little confused on how you wrote out the conditional rule for answer choice C for this question. Is there a video explaining how to write out these types of conditional rules, or if not, could you please explain?

Hi Bradley,

The video for sufficient and necessary would be helpful for unless conditions, which introduce a necessary condition. In this case, it is necessary for K to be assigned to T for F and M to both be assigned to T.

We could also diagram this as
If K not T -> F and M are T
and the contrapositive as
If not both of F and M are T -> K is T

I would also recommend looking at various office hours for the games. Seeing how different people approach diagraming different rules and questions can be helpful.
