    5/5. These seemed a lot easier than the last chaining questions but still happy with the progress

  • I'm getting really stuck with group 4 negate, necessary conditionals. For question four how do we get Invited > RSVP? I think I'm getting boggled down by the double-negatives...

    "NO (indicator) one is invited (idea 1) who did not RSVP (idea 2)."

    So then if the rule is to pick either, negate it, and make it necessary, then wouldn't you get this breakdown?

    One is invited > /RSVP

    Contrapositive: RSVP > /one is invited

    I realize logically this is flawed -- if one RSVPs, you could make a strong inferrence that they were invited... Am I making sense? Where am I getting crossed up?

    The ume fails the necessary condition (blooming for 3+ months) so it must fail the sufficient condition (amenable to tastes)

    for 5, how do these

    /3+ months > ume

    amenable > 3+ months 

    AKA

    /A>B

    or

    /B>A

    C> A

    mean B>/C?

    For question #5 you have to assume that an Ume is a tree, is that an assumption that a reasonable person would make without prior context?

    I still don't get why the conclusion in Question 2 is "Hermes likes to eat wasabi" and not "Hermes watches the Olympics and likes to eat wasabi".. why is watching the Olympics not included in the conclusion if that makes sense??

    So Just a pointer for anyone struggling.. some of these don't really need to be mapped out. For Example I noticed in the comments a lot of people were hung up on Question 5. I intuitively understood what the answer was before mapping it out. The Ume blooms from Dec-Jan, thats only 2 months. Only trees that bloom for 3 or more months are amenable to the emperor. Therefore, if Ume blooms for only 2 months it must be true that the Ume is not amenable to the tastes of the emperor. It's below the 3-month rule based on the set of facts. I hope this helps somewhat. We're all in this together, we got this!

    I am so lost that I dont even know what to ask for help on. I feel like I don't understand any of it. Is it really needed to learn the lawgic? Or can I just skip it? I feel like I just want to give up.

    Question 5 threw me off because I was trying to understand the first sentence as a sufficient and necessary condition. In reality, it is meant to be a statement that the ume is not a member of the set of "trees that bloom for three or more months".

    I did what he did in the video and got the answers he got in the videos correct. But on the actual questions when I clicked view answer, I got it wrong.

    #help For Q.4 my initial logic translation was the contrapositive /RSVP -> /I because I interpreter as the invite (I) as the negate necessary. Subsequently, Rudy affirmed the sufficient which triggers the necessary condition (/I). Is this the correct approach? I am confused.

    Q2: He maps the first sentence as a conditional claim (Gods of Mt O -> Watch Olympics). But isn't that just membership in a set? Bc to map it that way implies the contrapositive is true, and I dont think that holds based on the sentence (/Watch Olympics -> /Gods of Mt O). What am I missing here?

    Im super annoyed. I thought I mapped 5 correctly but he still mapped it in revers of what I did.

    Anyone hung up on Question 5, here is how I map it out.

    Ume -> Blooms December to January -> blooms 2 months -> /bloom 3+ months

    Amenable -> bloom 3+ months.

    /3+ months -> /Amenable

    Ume -> /Amenable

    could you also say, for Question 1, that Andrew is not a non swimmer? That's where my mind went at first. Andrew is a swimmer ofc, but he could also be not a non swimmer?

    When you have a double "negative", like in question 4, no X , ... did not Y, is the usual lawgic translation then X -> Y? Thats kinda a pattern I'm noticing but idk if that always holds true.
