#math why

[stranger-detective]

Okay just saw a post where someone was talking about the correct order to do maths in an equation acronym and they said 'PEMDAS'??? I learned BEDMAS wtf is this shit

so

These are the only ones I've heard but idk there may be more

#maths #this is some fucked up shit right here #why are there so many acronyms?????

Tell me why colleges require math classes that I am never going to need? Why do I need  to pay this much money to learn about math I am never going to need in life? Who needs to know this?

#rant #college is hell #college is too damn expensive #math why

luffy knowing a bit too much information about beetles and zoro being oddly good at math are concepts that make me extremely happy for no reason

#actually the reason is that they're often seen as idiots but they just think differently #and also they're pretty much neurodivergent #luffy infodumping about beetles and zoro is like 'uh yeah sure captain' *didn't understand shit but luffy is happy so it's fine* #zoro explaining the most complicated equation known to mankind bc of some dumb new attack and luffy's like #'why are you using letters? math is with numbers haha silly zoro' #they're so real for all of this #zolu #roronoa zoro #monkey d. luffy #one piece

Math

Geologist: I do more math than you might think

Chemist: I mean, chemical equations are basically mathematical equations. If you think about it (I also do math math)

Physicist: Oh, yeah, it’s all math but we just handwave it

Mathematician: YOU DO WHAT!?

Quantum Physicist: *regularly does math that is literally beyond human comprehension* *now resides in a higher plane of existence*

Engineer: If I don’t do this math correctly PEOPLE WILL DIE

Military Scientist: If I don’t do this math correctly PEOPLE WILL SURVIVE

Topologist: If I don’t do this math correctly PEOPLE WILL BE MOSTLY UNAFFECTED

Philosopher: But what even IS math, really? No seriously, what is it?

Organic Chemist: I kinda forgot how to do math, to be honest

Doing the maths: Grian's failure at getting a mending book

lots of talk about maths and probabilities below the cut! but there's a graph and simple explanation at the end if you want to get the gist of it and are bad at maths.

(I am still young and learning maths, critique/advice always welcomed)

What are the odds of getting a mending book in Minecraft?

(I am assuming Grian has been doing all his fishing with Luck of the Sea 3)

The probability of a mending book is actually a bit annoying to estimate. The Minecraft Wiki lists fishing up an enchanted book as 1.9% chance. This is for ANY enchanted book. The Minecraft wiki talks about how the chance of an enchantment being selected is calculated. Mending has a weight of 2. Using the table, mending has a probability of 2/135.

However, Grian is looking for any book with mending, not just a pure mending book. Additional enchantments are calculated in a different way, involving RNG, which means it won't be as easy to model. Due to this reason, I'll just be using the odds for a pure mending book throughout.

TLDR: a mending book has a 0.028..% chance (2/135*0.019*100)

Grian's Data

According to this screenshot, Grian has used a fishing rod 5679 times. This number may not be fully accurate, as it includes the times he's fished other players, rather than just fished for items, but it is a good estimate.

To help visualise this data, with a median waiting time between catches of 17.5 seconds, Grian has spent over 20 hours fishing so far! He may have a problem.

Is this statistically significant?

Hypothesis testing (p-value approach):

H0: p = 19/67500 (the null hypothesis - he has no mending books because of chance)

H1: p < 19/67500 (the alternate hypothesis - he has no mending books due to different odds)

5679 trials, 0 mending books

X ~ B(5679, 19/67500) (binomial distribution, 5679 tries with a probability of a mending book being 19/67500, where X is the number of mending books)

p(X=0) (what is the probability the number of mending books being 0)

p = 0.2021473392

Now, the point at which data becomes significant is subjective. For instance, you *could* get a million heads in a row flipping a coin, it's not impossible, but at a certain point, you can begin to say "okay there's something not normal about this". For this approach, the closer the p-value is to 0, the more evidence there is against the null hypothesis . The p-value here is far above a significance level of 0.01, or 0.05, or 0.1. There isn't a clear line between significant/non-significant, but this is answer is quite a bit far from 0

With this, I cannot reject the null hypothesis.

Personal conclusion: this is not statistically significant, Grian is just unlucky.

Are other values statistically significant?

Gem's proposed 9000: results in a p-value of 0.079... more significant than Grian's number but I don't imagine Mojang would be too concerned. As said though, it's all subjective.

I am bad at maths, what does all this mean?

Here is a graph, showing what number of mending books you might have after 5679 tries. The height of the bar represents the probability of getting that amount. The numbers at the top are the (rounded) numbers I used in my calculation

The pink column is 0 mending books - like what Grian has! As you can see, it is less likely than getting 1 or 2 books, but not too uncommon to happen.

End conclusion: Grian has bad luck. Like, not as hilariously bad as he thinks, but still bad. If he keeps going, chances are he will get a mending book, but I think he should probably stop fishing because at this point he has a problem.

#if you saw my last post no you didnt #<- misread “5679 fishing rods used” as having fully used up 5679 fishing rods #this is so much better written than my last post though. and i think the graph helps a lot #long post #locus fandom time #locus maths time #grian #hermitcraft #hermitblr #hermitcraft 10 #“why the p value approach” i missed the lesson for it so this is my catch up work unironically

Tumblr has no idea what to talk about so math is number one trending

i was rewatching enies lobby, and theres a scene where luffy asks zoro a math question, and granted, it’s an easy multiplication, but i had a thought. what if...what if zoro is just really good at math for no reason?

#luffy #zoro #one piece #enies lobby #comic #zoro is really good at math #of course luffy has no way to know zoros answers are right #but i think its funny anyways #the real question is #why did luffy ask if he didnt think zoro knew

I absolutely love every time other people find something out about Steve and are just like ???

I wonder if any of his student’s parents are fans of Eddie’s but have no idea their kid’s teacher is married to him (perhaps finding out at career day 👀)

I love the thought of some rock n roll dad (aka: the guy in the minivan blaring Rage Against the Machine during morning drop off (aka: aka: my dad)) meeting his kid’s teacher during open house and seeing a picture on his desk of him and guitar legend, Eddie Munson.

Steve’s in the middle of explaining the curriculum for the year when Rock N Roll Dad points to a picture of him and Eddie backstage at the Rock N Roll Hall of Fame last year when Eddie presented like, “You like that guy?”

Steve looks from Rock N Roll Dad to the picture and then back, “Yeah, you could say that.”

Then he goes back to talking about what they should expect in terms of homework and that was that until parent/teacher conferences.

The first thing Rock N Roll Dad clocks in the new picture on Steve’s desk. It replaced the Eddie Munson one with a new one of the two of them in the parking lot after a local show. Steve’s got his arm thrown around Eddie’s neck, both of them smiling wide, and Gareth is in the background giving them bunny ears.

Rock N Roll Dad points to the framed picture like, “Pretty cool to have met ‘em.”  

“Yeah,” Steve nods. “It’s one of the best things that’s ever happened to me.”

Rock N Roll Dad is not gay himself but he is not one of those ultra straight Corroded Coffin fans that liked to pretend that half the band isn’t queer. He was actually watching the MTV Music Awards show that Eddie publicly came out at by declaring his love for some guy named Steve, and actually.

Rock N Roll Dad thought it made a lot of sense that Eddie Munson was gay because well. A lot of his songs were… phallic.

So, he knows.

He knows that Eddie Munson is gay and that he’s married to some guy whose name isn’t even listed on his Wikipedia page, and he knows that he lives in Chicago, but what he doesn’t know is why he never put two and two together and got Steve Harrington.

There’s a different picture of Eddie Munson on Mr. Harrington’s desk when Rock N Roll Dad goes to talk to him after his kid gets detention for being a little shithead. There is framed original concept art for CC’s first album on the wall behind Steve when Rock N Roll Dad checks in on his kid during a zoom study session.

Hell, Rock N Roll Dad follows Eddie on Tiktok.

He has seen the ass shots that Eddie has posted of his husband in his running shorts, and he did think, yeah, that’s a great ass. He didn’t know he was thinking that about his kid’s math teacher!!

It’s not even Career Day when he discovers it. It’s the day before when they can set up their booths in the gym because Rock N Roll Dad may be a heavy metal fan always, but he’s also an accountant from 8:30 to 4:30 Monday thru Friday.

 He’s struggling to keep his poster board up when in walks guitar legend, Eddie Munson. He’s carrying a box, following behind a guy carrying an iguana.

Rock N Roll Dad abandons everything and walks over to the booth across the way. He can hear the two bickering with each other but before he can say anything, Steve Harrington is there and he is distressed, “Why do you have that?!”

“Her name is Leia, Steve,” Dustin says, “and she has separation anxiety.”

Steve opens his mouth like he wants to complain but doesn’t even know where to begin so he just accepts it, “Is she going to eat somebody?”

“That happened one time!”

Eddie Munson, infamous guitarist that lived on Rock N Roll Dad’s walls as a teenager, uses the opportunity to slide up next to Mr. Harrington and wrap an arm around him. He kisses his cheek, “Baby, we’re here to help.”

“You’re here to guilt me into letting you be a part of Career Day.”

“I can multitask, babe,” Eddie grinned, still so close to Steve that his smile touches his cheek. Steve just sags against him and Rock N Roll Dad thinks, oh. He thinks, oh, shit.

“You have a fan,” Steve mumbles, pulling away a little. It takes Rock N Roll Dad a second to realize that they’re talking about him and then he thinks, fuck.

“Hey – Hi. Uh.” He stops, thinks about lying and saying he needs tape or something, but settles on, “I didn’t know my kid’s teacher married you.”

“Technically, I married him.”

“Technically, I married both of you,” Dustin pointed out. “I officiated the wedding.”

“Ah,” Rock N Roll Dad says because what else is there to say. “Big fan.”

“Yeah, I can tell.”

#at this point in the timeline Steve has only been shot from waist down in Eddie’s Tiktok account #you may be thinking ‘is rock n roll dad Jeremy’s dad’ and he’s not #he’s the father of a kid that doesn’t give a shit about how their teacher is married to so when he goes home and says your math teacher is #married to a celebrity they’re like ‘I don’t know who that is so no he’s not’ #so Steve’s students don’t find out until Eddie’s infamous ‘why is your math teacher my husband’ Tiktok #eddie munson tiktok saga #steve harrington #eddie munson
