Three people are selected at random from a group of 11 men and 7 women. What are the odds that...
a) at least one man is selected
b) two men and a woman are selected
How do I do this? I'm trying to study for a test but I don't know how to approach this problem.
go back to /mu/
>>7668844
I've never been to /mu/ and I don't plan on going there. I need to figure this out.

What happens when we put the cat's free will into the equations? Does it eliminate the paradox?
>>7668829
It eliminates almost every question we've ever had.
>>7668829
Free will does not exist.
yeah
It is said the real number system has only one infintisimal, the number zero. This is, of course, is a heap of rubbish. Negative numbers are smaller than zero thus the real number system actually has an infinite amount of nonZero infinatesmals. This is ir-refutable.
Bech, I'll teach you.

I'll preemptively throw out there that the common scientific understanding is that it is the net result of the balance between the sympathetic/parasympathetic nervous system, the electro-chemical signals fired off by the responses to the environment (even in cases where all stimulus is removed; sensory deprivation, induced coma like states, acute/chronic altered and/or diminished mental status), and the conception of the "self" as self-realization occurs and is processed by the individual.
The commonly shared theological understanding is that "consciousness"...

Yes.
We dont even know how the brain works, the only asnwers you're going to get are shitposting or religious or spiritual bullshit

Yes?
Bane?
I'm in university; it's my first year. I'm taking Calculus 1, Intro to Physics, and Organismal Biology, as well as a few Arts courses. Next semester, I'm taking General Chemistry, Calculus 2, and the rest of my arts courses. I'm going towards my Bachelor's of Arts and Science. What does my future look like (i.e. what can I expect from the harder Calculus courses and what can I actually do with this degree?).
>>7668707
I see a McDonalds uniform in your future.
>>7668709
why is that? I'm taking the 'real' courses for the majority of my degree, does the Arts in the title really tarnish the rep that much?

What does /sci/ think about flu vaccines?
How many things can one get vaccinated against? Does anyone think prayers are more effective
Meh.
Like 3-5% effective because there are so many types of flus and they basically guess which one will be prevalent each year.
I never get the flu, hence I'm not too worried about preventing it.
Inject something that directly interacts with your immune system with little to no clear benefit.
I pass every year. No thanks.
Adult influenza vaccine injury claims are now the leading claim submitted to the federal Vaccine Injury Compensation Program so it is important to understand risks associated with influenza vaccines. Below are current links for the influenza vaccine manufacturer's package inserts that have been licensed for use in the U.S. NVIC encourages consumers read this information carefully prior to receiving a vaccine. These links will lead you to the U.S. Food & Drug Administration's website, which makes vaccine package inserts and licensing information from available to...

So i got gifted one of these badboys (was still in original packaging with book)
I'd really like to learn more about math, as silly as it seems would pairing this up with kerbal space program be a great way to learn physics and shit?
This has some form of ti-basic, i figure i can eventually learn how to properly launch a shuttle, and write a program to help me with that. (i do development for a living i'm not scared of learning basic)
I just feel when it comes to math i'm a bit retarded, and wouldn't know where to start.
I'd...

u should read a book

i cant into math
whats a basic physics book, that would help me learn enough basic physics to learn about pushing a shuttle into space
i know i need to read a book
no idea what book

Have you done the work and studied the material? Then what is there to worry about.
>>7668565
I have anatomy exam in 2 days. With 4 books to study from. It takes me at least 1 day to revise 1 book so its been 3 days since I studied book 1. As everything is to be remembered and not concept based, its easier to forget. And I feel like I dont remember the stuff I studied first.

I bet you get angry when other people don't have the same low standards as you, and refuse to eat garbage.
I would like to ask for insights and speculations into the future of coding and programming.
Is the field changing in a particularly meaningful way?
Will programming skills be valuable to have in the job market of the years to come?
>Is the field changing in a particularly meaningful way?
As the performance of things increase, people get lazy and forget to optimize/clean up as much, so code over the years will get really bad and turn to be more hoggier of resources over the years.
>Will programming skills be valuable to have in the job market of the years to come?
If you're a good at it, as in the ability to think on how to sucessfully do something well, neat, tidy, understandably and effectively, you will be no doubt in the top...

Business "programming" in the future will be similar to making a PowerPoint presentation. It's already pretty much this in a lot of situations. The business will have some software package, say for web forms, and will hire a "programmer" to work with it. That "programmer" will spend his days selecting widgets off a menu and setting their properties.
There will always be some need for lower-level programming, but the majority of people in business data departments won't really have any programming skill.
I feel like with the transition in electronics towards smaller and smaller and the introduction of quantum computing I feel like we'll need people who understand basics of electronics and can code close to the hardware. The more lights and shit are moved to the internet the more pressure is on embedding systems.
What are the asbestos/lead piping versions of this generation? As in, what (in the future tense), retrospectively very common chemicals or materials that are being used everywhere right now will end up being understood to have been terrible for human health? I'm assuming certain plastics and GMO's will become this, but I'm sure there is more
>>7668469
There are several fire retardants (for plastic and paint additives) which materials engineers are intentionally using that we know kills any anyone in the immediate vicinity very quickly once vaporized (happens immediately upon heating even before combustion) and on which the effects of long term exposure to minute concentrations have not been extensively studied.
However, modern infrastructure can not exist without these FRs because entire city blocks could easily burn down due to just one moron putting out...

How does /sci/ feel towards the current primary, secondary and tertiary educational systems?
>>7668236
/sci/ is american so probably won't feel any way. I am not but I also have no feelings towards it. Now I'm out of it let the other kids burn I say.

Too fucking slow and doesn't cover nearly enough material.

People not interested in learning need to get the fuck out.

Sine about 1950 problems have compounded each other to the point where the public K12 system is almost unsalavgable.
First, integration needed to occur (inb4 /pol/ shows up). The shock of it has never been resolved. Then schools stopped getting enough money to operate. Then teachers unions went full strike mode because they don't want their pay cut or any sort of accountability introduced on their end. What we have now is a huge fucking mess. Affirmative Action court orders from the 60s go up against...

Is this bullshit or not? I lack the competence to tell. Is this considered refuted?

http://www.simulation-argument.com/simulation.html
It's not disprovable in any case, just a modern version of Descartes' demon they're using to sell books to you.
Anyway, I would like to point out that the "simulation argument" doesn't really stack with evidence that physical properties are quantized, etc. in terms of credibility. Not in the way you might think it does at least. I mean, are they saying these artifacts of the simulation are present in the real-real world or not? If they are, then all it indicates is that reality is simulable. If they're not there then our world has already...

>Would the knowledge that you are living in a simulation, with no way to know the kind of simulation it was, carry any moral weight? Would you do anything differently?
No, I would not, because the "simulation" would still be all the "reality" we will ever know. It is practically indisguishable from reality.
Subject is still interesting tho
>>7668282
I would look for a way to threaten the stability of the simulation so that I could get in contact with the runners of the simulation and try and force them to give me a robot body in their world.
Nah, just kidding, I'd tug at the stability of the universe if the opportunity arose even if I didn't think I was in a simulation.
Why does /sci/ hate on engineering so much, but glorify pure math and science? All that engineering is is pretty much using what scientists and mathematicians have discovered to create/modify stuff. In order to do this, engineers have to understand what scientists from a range of fields understand...
Soooo...what's the problem here?
>>7668192
I'm not sure to be honest. I happen to think anything involving science or math is worth the praise. Computer science too, but /sci/ doesn't like CS majors either. Maybe it's because people here just like to argue and show off how much they know in one field.
>>7668192
Because it's easier to pretend to be a theoretical scientist or a mathematician than it is an engineer.
Engineers usually actually produce something. It would be quite a feat to convince yourself that you are an engineer if you haven't done jack shit in your life. On the other hand, the work of a mathematician or theoretical scientist is usually more ephemeral, their work might not bear physical fruit in their lifetime and sometimes it is entirely theoretical. Much easier to delude yourself into...

We don't. There's one really autistic physics drop out that thinks engineering is blasphemy to the church of physics that used to spam gay porn and one tryhard kid that parrots him to fit in here.
