You are a biologist traveling through a rainforest and you are bitten by a venomous snake. Luckily you know the venom can be neutralized by licking the back of the male of a certain species of frog. You also know that only females of this species croak, males and females are otherwise indistinguishable from a distance, positioning and croaking behavior of a frog is random and independent from other frogs, and the population is evenly split between males and females and can be considered arbitrarily large.

Luckily you see a frog of this species in front of you. You then hear a croak behind you and turn around to see a pair of the same species of frog where the croak came from. You only have enough time to run and lick the lone frog or the pair. Which direction do you run and what is your chance of survival?

Okay, then don't.
It is, it's a fakeass problem so people are making up parameters on the fly. What if the frogs croak just a few times per day, or at some specific time like a cuckoo... It's literally that you are licking one uncroaking frog in both instances. Either one you choose is equally likely as the other.
>it's a fakeass problem so people are making up parameters on the fly.
How is it "fakeass?"

>What if the frogs croak just a few times per day, or at some specific time like a cuckoo...
Then it's still not 50%.

>It's literally that you are licking one uncroaking frog in both instances.
Right, and that frog is more than 50% likely to be male.
Yes yes. A very confounding problem indeed.
Thankfully, because I am very smart, I did my research on the venomous species in the area well before embarking on my journey through the jungle. To prepare I captured over 100 frogs and placed them all in a burlap sack to carry with me.
Now instead of having to waste precious moment chasing after and catching frogs, I merely open my bag and begin licking as many frogs as I possibly can. Why, I can lick frogs so fast I bet I could get 50 licks in.
So what are my chances of survival now? I have no fucking idea. I am a biologist after all; I can't do math.
But my chances of survival are most certainly higher than some weenie who we into the jungle without a sack of 100 frogs.
The croaking one is 100% male. You can't determine the odds of the others without knowing how often these fucks croak.

/math/ i keep on getting these hilarious captchas, this can't be random.
they gotta be seeding the randomness that creates the captchas with memes, is there a mathematical way to prove it?
17 replies and 7 images omitted. Click here to view.
This. You're ignoring the vast quantity of captchas which don't present any word patterns, thus minimizing your sample space to only those patterns which your brain likes to remember.
What if I got A D G V X as my captcha? That's unbelievable! What are the odds???!?!?!?!

No? Not that awesome? But what are the odds I'd get that EXACT string of letters?

What? It doesn't spell out anything? But it was just as likely to pop up as any other captcha! This proves it's not random!!!!!
If you think that sounds retarded, then at least you're not retarded enough to see why the confirmation bias exists.

I figured out gravity, its just cosmic slowdown like a shooter on the snes when theres loads of bullets on screen

Any given area of space can only process so much information at one time. the more information there is in an area, the longer it takes to fully process that information. energy oscillating between different information densitys will spend longer in the slower rate, and thus be pulled towards it.

Therefore gravity is not an effect of space time curvature, but the net delta between processing rates.

How do i collect my nobel prize?
You know, you can literally go and simulate this in like 500 lines of Python. Go see if it looks like gravity. I don't see it working at all, because under your model, gravity has an exponential pull relative to density.
So can I increase gravity by producing a huge fart? How big would the fart need to be to effect the gravity within my local environment?
i know cpp il give it a go, im not sure i see your point though
no because your shart is already brewing in your guts, if anything the processing speed of your area of space will increase as the volatiles dissipate and the shit crusts up around your ass and leg area

yeah yeah you can argue that it's putting old ideas in a new light, but it's still novel philosophy
Wouldn't be so bad to take humanities courses if contemporary academia wasn't on the lunatic fringe. America's institutions are sick.
You mean anti-humanities? Because that is what it really is.
Consider a christian uni. Thats what I did. Required bible classes, but I avoided the fag/tranny/blm train.
Not sure how it is now, but when attended almost 10 years ago, the required culture/humanities class was western history, and they pulled the vast majority of african american content and pushed it to another class that no one took(offered only one half semester a year), as it was a >95% white campus, and the rest were hispanics and asians.
You literally took remedial calculus in college, a course made for retards. Of couse you love when daddy education tells you what to do. It is also no suprise you're spouting memes such as:
> make you a well rounded human being
as if it was necessarily the purpose of college to "educate" you on all aspects; as if what they teach you was a general knowledge; and as if all this crap had anything to do with being hu;am at all.

how do i teach my kid to add subtract and multiply numbers at age 4?
6 replies omitted. Click here to view.
you want your child to try and impress the college people so they stop thinking your family is goyim you asking your kids to wear a mask and act like they are better will only cause mental unwellness for the sake of pleasing large corporations that want them to earn a certain amount of grades in order to get into college where they will then be 60k in debt
i am nto american, i am Polish.

he can already count to 100 because i drew him little kids books about counting numbers. i understand to not force it on him because i myself was forced by my parents to read at age 3.

>we need to fix everything in the trees before we can even THINK about moving to the ground
Apes didn't get down from the trees because they had fantasies about the life on the ground. They did it because the ancient Africa wide forest turned into a savanna and they had no fucking choice.
Even if Starship is ready for Mars trips by 2026, development of colony hardware is in a much worse state. Two decades if we're lucky.
If a supervolcano wakes up and everything turns into hellscape for a while before relaxing to just ruins under endless ash clouds that block enough sunlight for most of vegetation to die, then it will be a bit too late to investigate off-world colonies.

because economics is a pseudoscience, so they use mathematical equations to give "the illusion of science without any of its substance."
Lol now you are stealing the "math is a language" meme. It isn't true, math books are mostly text and verbal explanation, every mathematical operation has text to explain whats going on. Math symbols are just shortcuts to avoid excessive text when you are referring to the same concept multiple times, so you can write 2+2 instead of typing "now you add upp the numbers 2 and 2".
Physicists are more respected, in the same way that monks and intellectuals are respected. It has nothing to do with money. NBA nogs make more money and nobody respects some bouncyballer.
What about Math, Science, and History?
How does this refute anything he said? Physicists also use math to explain things. This isn’t something unique to economics.

Started hobby collecting old books about 2 years ago, mainly classroom math/science/history books. Most of them are from 1800's - 1910. Quickly notice, despite the stilted writing style, it's much easier to understand concepts from these old books compared to their modern day equivalents. Information is concise, examples/explanations are not midwit word problems or analogys, amazing pictures and diagrams. My largest epiphany of how fucked books are hits me when I get hold of a 1800's medical book called "A text-book of human physiology" by Flint, Austin. It has amazing in-depth explanations and detailed gorgeous hand drawn diagrams, you can't find anything like this online or is most basic medical books.

WTF happened? I realize information has been "dumbed-down" or even censored but still I never knew it was to such a great extent.

Incentives. Why be publicly passionate when your hindbrain knows you'll just get torn to shreds for every shibboleth you mispronounce, and it's impossible to remember all of them? In the old era, there was a lower number of shibboleths you had to remember to cover your bases. Not only that, but the other elites whose opinions you cared about were sometimes themselves actually consistently capable of appreciating original genius. So if you were of the educated class, then, unlike now, if you had it, it paid to flaunt it. Now no one flaunts it -> no one has it -> no one flaunts it, in a seemingly endless shame sink. But it'll end one day.
Fear of spiders, shit like that is proof of Telogony.
