    Can we say that due to the contrapositive not being about the subject and predicate that this is incorrect as well?

    most fruity things are tasty fruity ---m-->tasty /fruity--m->/tasty most non fruity things aren't tasty ( obviously this isn't true a lot of non fruity things are tasty)

    [...]

    I don't know how to include my explanation but it has to do with using sets and images which are not included.

  • All or None are absolute quantities, so those are bidirectional as well? Shouldnt those terms be included in some then?

    So conditional statements with these quantifiable terms have no contrapositive. They might try to test us on this on the LSAT.

    There are no contrapositives for ←s→ and ‑m→

    Does a most relationship not imply a some relationship if flipped? So "Most otters are burglars" would be O --most--> B. If you flip it would it not be correct to say "Some burglars are otters" or B ←s→ O since the most implies overlap already?

  • I thought you could negate some with all or none

    Why doesn't a contrapositive of "some statements" turn to "no statements" work? Since "some statements" have a lower bound of at least one why doesn't the negated statement become "not at least one or none"

    Some Dogs are mean (AT LEAST one or more dog is mean)

    why isn't the negated : no dog is mean

    wouldnt a most claim also imply a some claim?

    Most dogs are pets

    This implies:

    Some dogs are pets, which is reversable to some pets are dogs

    #feedback I feel like the use of the word "nice" here is conflating negation with opposition

    Logically equivalent would mean it has the same quantifier.

    wouldn't it be inferred that

    a--- Most ---> b

    also says

    B A

    although i see it is not a contrapositive

    Under review section what this law fix statement mean:

    not imply /A ←s→ /B.

    so if A ←s→ B does not imply /A ←s→ /B, can we claim that this B ←s→ A is true instead?

    Can't you flip most A are B (A ‑m→ B) to some B are A (B ←s→ A)

    you cannot "flip and negate" on the "some" or "most" arrows. "Flip and negate" (the contrapositive) is just for conditional claims.

    What about the quantifier for every and any? We Can transulate the contra positive correct?
