Welcome to femcel memes. A place where anybody can post memes that fit the vibe.

Warning: We have a tendency to post things that may at times come from a self-deprecating perspective or things that are funny coming from another queer person. This space will always be a safe place for transfems, non-binary people, people with a feminine gender expression (GNC or otherwise) or anybody else in the LGBT Community to come together and share about our experiences but we truly feel that laughing about the sometimes silly and embarrassing parts the queer experience can help bring us together. We never mean offense or harm in anything posted but rather they are satirical takes coming from queer people.

A note about 'Egging': Our community is mostly made up of transfem individuals, and as such most memes posted will be posted with the intention of having a transfem perspective. However, regardless of gender identity, all feminine presenting individuals are welcome here. Whether that means you're NB, GNC, transmasc, or any other identity, you are welcome here. It is not our intention or goal to invalidate these identities. If something makes you uncomfortable, please feel free to report the post and I will address your concerns on an individual level. For more information regarding the problems with 'Egg-culture', please see Here.

Love Y'all and thank you for following this community

Oooh! This is a great solution to this problem! Just write down both numbers and perform a luhn check:

https://en.wikipedia.org/wiki/Luhn_algorithm

The one that lies only has a 1 in 10 chance of making up a number that will pass the check! Cool shortcut: If it starts with a 1, 2, 7, 8, or 9, they're lying. Those are reserved for things that aren't credit cards ๐Ÿ‘

But you only can ask one question and asking for their CC information won't help you find the exit.

Did you not read the comic?

You make a good point there...

I thought credit card numbers were just for credit cards, what are the "things that aren't credit cards"? Genuine question I'm just curious.

[โ€“] riskable@programming.dev 2 points 2 weeks ago (1 children)

1,2: Airline cards (e.g. Lufthansa)

7: Gas cards (Shell, Mobile)

8: Health-related and telecom cards (remember those old Sprint calling cards? That)

9: Reserved.

3,4,5, and 6 are the only types that would count as "credit cards".

Interesting!

This kinda falls apart with the knights talking at the start. Either there is 1 that only tells truth with the other not being bound by those rules or one that only tells lies with the other one doing whatever since one of those 2 is telling a lie.

That's a good point actually, they kinda messed that part up a bit

For those interested, ignoring the contradictory presentation of the riddle (as the knights themselves would not say the riddle since one always lies and one always tells the truth), the solution is simple. Ask the knights what the other knight would answer when asked what door is correct, and they will both say which path not to go to. Thus you pick the path that neither Knight says!

Logic:

Liar: Will say the wrong option, as they're being asked which door the truth telling knight would say (and they will lie about what the truth-teller would say)
------------------------------------------
Truth-teller: Will say the wrong option, as they're being asked which door the liar would say (and they'll tell the truth about that)

NOTE: This can be expanded to a case with n doors by asking the knights to provide all the options that the other knight could say, and each will provide n-1 options, so you'd pick the one option that neither knight says. It is possible the liar may not list all options, but the truth-teller would, so the problem could still be worked out regardless (and you'd know which knight is the liar in that case).

The easiest solution is to ask what is the color of their capes that they are wearing

[โ€“] ArachnidMania@lemmy.ca 6 points 2 weeks ago (1 children)

You've then found out which one lies, but you've used up your one question and now don't know what is the correct door to leave.

[โ€“] PrivateNoob@sopuli.xyz 3 points 2 weeks ago

Oh shit that's true

[โ€“] petersr@lemmy.world 3 points 2 weeks ago

Am I mistaken for recalling that in the original riddle, the question should have a boolean outcome (yes/no)?

Having a question with a big domain makes it a lot easier to guess what is a false and true outcome.
