If Iris is scheduled for Wednesday, which one of the following must be true?

Why are h/n binary?

I don't understand why there is a H/N binary for Thursday and Friday. Since the contrapositive of the second rule says that if I is not on Monday, N is not on Thursday, how could N be potential option for Thursday here?

Hello @ahug,

I think you may have misread this rule and mixed up Tuesday and Thursday.

The contrapositive of the third rule says:
If Iris is not scheduled for Monday, then Nancy is not scheduled for Tuesday.

To avoid this, I usually use "R" to represent Thursday in my diagrams.

Here the video explanation jumps into #10!!! I'm having this issue with all LG explanations either they jump questions or omit questions in the explanations. Where can I find the full version?

I have the same issue. Why are the explanations only covering the last question and simply skips over the rest? Would be really helpful to hear the explanations for the other questions too.
