티비냥 ENGSPAIND RM Confused By His Own Answer Problematic Men 150709

(We're a variety show... Someone talk...) (People starting to give up) [TV Meow] Four people who went to the tropical fish store heard this explanation from the owner "All of the blue-scaled Arowanas have red eyes and eat crickets" "All of the Arowanas that eat crickets eat goldfish" Who is the person who understood the shopkeeper correctly? Ji Woo: Arowanas that eat crickets and don't have blue scales, have red eyes Shin Woo: Arowanas that have red eyes and eat goldfish will also eat crickets Min Soo: Arowanas with red eyes and no blue scales eat goldfish Jun Beom: Arowanas that eat goldfish with no red eyes don't have blue scales [Hyun Moo] What are they on about Although they eat crickets (Slowly) Arowanas that don't have blue scales Arowanas that eat crickets (Staring blatantly) (RM writing everything down) (We're a variety show... Someone talk...) (Sigh) (People starting to give up) (An expert at giving up) I dunno... I get confused by my own writing Try Jun Beom as the answer, I got Jun Beom I think it's Jun Beom too - Jun Beom, right? - [Tyler] It's Jun Beom - Who's question is this? - RM - RM will you try? - I got Jun Beom too I can't say why it's not Jun Beom You think its Jun Beom because the rest aren't it, right? [Hyun Moo] The rest aren't it (Getting up out of habit) I'll explain it Try explaining each sentence We'll call the Arowanas with blue scales 'B' Or 'BA' for And there's 'RE' for red eyed Arwaonas And Arowanas that eat crickets will be 'CE' And Arowanas that eat goldfish will be 'GE' These are the only Arowanas, right? The 'BA' Is an 'RE' as well and a 'CE' too And 'CE' is undoubtedly 'GE' These are the conditions given This mean this, This mean this - Then we can mix them - Yea, we can Then 'BE' is 'RE' and also an 'CE' and finally a 'GE' If we write this down We'll I guess your proposition is correct Ji Woo said the 'CE's Are not 'BA's So this isn't right (~means incorrect answer) Its not 'BA' (~'BA') Then, 'CE' and 'BA' have 'RE's There's no way 'BA's can be 'RE's Ji Woo is completely wrong Shin Woo said 'RE's are 'GE's then said they are all 'CE's You can go from left to right but not right to left - It's all wrong - Yea, 'All' can't be the answer Only parts of it can be perfect, so Shin Woo is wrong And Min Soo said its 'RE' but not 'BA' The its '~BA' Then '~BA' all eat 'GE's [RM] You're getting confused now aren't you? If you draw it - [RM] You don't have to draw it - No, I drew a picture - It's Jun Bum, no? - [Seok Jin] It is Jun Beom but [RM] Jun Beom is right, no doubt 'BA' is undoubtedly in here (a = 'BA') (Drawing a venn diagram) This is 'CE' (c = 'CE') And this is 'RE' (b = 'RE') 'RE' How are you going to draw 'GE'? Oh, it said Arowanas that are 'CE's are also 'GE's Then this is 'GE' (d = 'GE') Then you just have to find the wrong statement Ji Woo: Arowanas that eat crickets and don't have blue scales It's right here [Hyun Moo] So? [Hyun Moo] What about the red eyes statement? Because this area is blank, he's wrong (Since this area is not included) Shin Woo: Arowanas that have red eyes and eat goldfish It's here, right? [Hyun Moo] And? It's wrong because this area isn't included [Hyun Moo] Don't color the venn diagram, it gets so confusing Min Soo said that Arowanas with red eyes and no blue scales Which is the rest except this part All eat gold fish Is wrong because this area is still left Lastly, Jun Beom Arowanas that eat gold fish but don't have red eyes Excluding this part, Arowanas that eat goldfish but don't have red eyes don't have blue scales [Hyun Moo] Correct, he's got it I just read each sentence That method confuses you But if you approach it like this, it's easy
